Pakati pa matailosi owoneka bwino ndi khungu, lomwe ndi khungu la matailosi, zomwe zimapangitsa kuti miyala ikhale golide, imapereka mitsempha ya ceramic. Popanga matailosi owoneka bwino, magwiridwe antchito okhazikika a glaze hare ayenera kutsata, kuti akwaniritse zokolola zambiri komanso zabwino. Zizindikiro zazikulu za ntchito yake zimaphatikizapo kuwoneka kuti zikuwoneka, kufalikira, kufalikira, kuyimitsidwa, kugwirizira thupi komanso kusalala. Mwakupanga, timakwaniritsa zofunikira zathu popanga zigawo za ceramic raw, ofunikira kwambiri kusinthira ma visteki, nthawi yomwe masentimita ali nawonso ali ndi mphamvu. Sodium katatu patatulphosphate ndi madzi amadzimadzi Syvinem PC67 kukhala ndi ntchito zobalalitsa ndikuwonetsa, ndipo chosungira ndikupha mabakiteriya ndi tizilombo toyambitsa methyl cellulose. Panthawi yosungirako kwa nthawi yayitali ya glaze scrorry, ma ion mu glaze scrourry ndi madzi kapena methyl amapanga zinthu zowonjezera, komanso gulu la methyl mu glaze slurry limachepa. Nkhaniyi imafotokoza za momwe zimaperekera methyl nthawi yokwanira kukhazikika kwa njira ya glaze yokhazikika imakhudzidwa kwambiri ndi methyl cmc, madzi ophimbidwa ndi Kaolin mu formula, ndondomeko yokonza, ndi kutalika.
1. Zotsatira za gulu la methyl (cmc) pazinthu za glaze scarry
Carboxymethyl cellulose cmc ndi polyinionic controukisi yosungunuka madzi atasinthidwa ndi mankhwala a chilengedwe (alkaliliali chlorose ndi makonda a chlorocetic acid. Makamaka amagwiritsa ntchito malo ake ogwirizanitsa, kusungidwa kwamadzi, kubalaku kwa kuyimitsidwa, komanso kungoyambira kuti apange glaze wa glaze wosalala ndi wadzimadzi. Pali zofunikira zosiyanasiyana pakukweza kwa cmc, ndipo imagawika m'magazi apamwamba, otsika, komanso otsika kwambiri. Magulu apamwamba komanso otsika-otsika methyl amapezeka makamaka ndikuwongolera kuwonongeka kwa cellulose - ndiye kuti, kuthyolako kwa cellulose ma unyolo. Zotsatira zofunika kwambiri zimayambitsidwa ndi mpweya mlengalenga. Zofunikira zomwe mukuchita pokonzekera mafayilo apamwamba kwambiri a cmc ndi chotchinga cha oxygen, nayitrogeni akutulutsa, kuzizira komanso kuzizira, kuwonjezera othandizira ogwiritsira ntchito mtanda. Malinga ndi kuwonera kwa chiwembu 1, Conmeme 2, ndi chiwembu 3, zitha kupezeka kuti ngakhale malo owoneka a mavi a Vithyl ndi otsika kuposa momwe kachilombo kakang'ono ka magazi ndikwabwino kuposa gulu lalitali-laving. Pankhani ya boma, gulu lotsika-ma visyl limakhala ndi maxidi ochulukirapo kuposa gulu lalitali kwambiri la Vithyl ndipo lili ndi unyolo wamfupi. Malinga ndi lingaliro la Kukula kwa Endopy, ndilokhazikika kwambiri kuposa gulu lalitali kwambiri la maviyo. Chifukwa chake, kuti muchepetse kukhazikika kwa formula, mutha kuyesa kuchuluka kwa magulu otsika a mafayilo, kenako gwiritsani ntchito masentimita awiri kuti muchepetse kukwera, ndikupewa kusinthasintha kwakukulu kwa cmc imodzi.
2. Mphamvu ya kuchuluka kwa madzi kulowa mu mpira pa ntchito ya glaze
Madzi mu glaze formula ndiosiyana chifukwa cha njira zosiyanasiyana. Malinga ndi kuchuluka kwa magalamu a 38 mpaka 355 omwe amawonjezeredwa ndi magalamu owuma, madziwo amatha kupaka mafuta owuma ndikuthandizira kupera, komanso amathanso kuchepetsa phokoso la glaze. Pambuyo poona chiwembu 3 ndi chiwembu 9, titha kuwona kuti ngakhale kuthamanga kwa ma methyl gulu kulephera sikungakhudzidwe ndi kuchuluka kwa madzi, omwe ali ndi madzi ochepa amakhala osavuta kusunga komanso kusungidwa. Chifukwa chake, pakupanga kwathu, kuchuluka kwake kumatha kuyang'aniridwa pochepetsa kuchuluka kwa madzi kulowa mpira. Pazomera zopopera mpweya, mphamvu yokoka kwambiri ndi kupanga mtengo wokwera kwambiri kumatha kutengera, koma pokumana ndi spraze glaze, tiyenera kuwonjezera kuchuluka kwa methyl ndi madzi moyenera. Makulidwe a Glaze amagwiritsidwa ntchito kuwonetsetsa kuti malo owopa amakhala popanda ufa atathira madzi.
3. Zotsatira za Kaolin zomwe zili pa glaze slurry katundu
Kaolin ndi mchere wamba. Zigawo zake zazikulu ndi za Kaolibolite mchere wa Katrorillonite, Mica, chlorite, feldspar, ndi zina zambiri zomwe zimagwiritsidwa ntchito ngati alumina m'ma glazi. Kutengera njira yowoneka bwino, imasinthasintha pakati pa 7-15%. Poyerekeza chiwembu 3 ndi chiwembu 4, titha kuona kuti ndi kuchuluka kwa zomwe zakhala zikuchitika, kuchuluka kwa glaze slurry kumawonjezeka ndipo sikophweka kukhazikika. Izi ndichifukwa choti mafayilo akukhudzana ndi kapangidwe ka mchere, kukula kwa tinthu kukula ndi mtundu wa matope mu matope. Nthawi zambiri, zonena za Montmorigalonillonillonillononillonite, zomwe zimalimbikitsa, zomwe zimachitika chifukwa cha magazi mosayaka, motero sizophweka kusintha pakapita nthawi. Chifukwa chake, kwa glazis yomwe imafunikira kusungidwa kwa nthawi yayitali, tiyenera kuwonjezera zomwe kaolin.
4. Zotsatira za nthawi yopumira
Njira yophwanya mphero imayambitsa kuwonongeka kwa makina, kutentha, hydrolysis ndi kuwonongeka kwina kwa cmc. Kudzera m'fanizo la chiwembu 3, chiwembu 5 ndi chiwembu 7, titha kukweza koyamba kwa gulu la miyala yamtengo wapatali, kukoma kwamphamvu kwa nthawi yayitali, ndikosavuta kuwononga. Ngakhale zowonjezera zimawonjezeredwa nthawi yotsiriza mu mapulani 7, ngakhale ma viscy akukweranso chokulirapo, kulephera kulinso mwachangu. Izi ndichifukwa choti nthawi yayitali ma molecular, ndizosavuta kupeza mpweya wa methyl womwe umataya. Kuphatikiza apo, chifukwa kuchuluka kwa kuchuluka kwa mpira ndi kotsika chifukwa sikuwonjezeredwa musanayambe, kukongola kwa slurry kuli kokwera komanso mphamvu pakati pa kambuku kalankhulidwe kameneka ndi kocheperako.
5. Zotsatira za oteteza
Poyerekeza kuyesa 3 ndi kuyesa 6, glaze slurry yowonjezeredwa ndi oteteza ma viscly popanda kutsika kwa nthawi yayitali. Izi ndichifukwa choti zida zazikulu za cmc zimayengadwa, yomwe ndi yokhazikika polymer, ndipo glycosiidic yolumikizira michere yazosavuta, ya macromolecular yopanda ma molekyulu amodzi. Imapereka mphamvu yamagetsi yazithunzi ndipo imalola mabakiteriya kuti atulutsenso mwachangu. CMC itha kugwiritsidwa ntchito ngati kuyimitsidwa chifukwa cha kulemera kwake kwakukulu, choncho pambuyo pake pamakhala biodegrad, kukula kwake koyambirira kwa thupi kumathanso. Njira yogwiritsira ntchito mankhwala oteteza kuti athetse kupulumuka kwa tizilombo ta tizilombo tambiri timaonekera makamaka mu gawo la invaction. Choyamba, zimasokoneza ma enzymes a tizilombo tating'onoting'ono, ndipo zimalepheretsa ntchito ya ma enzyme; Kachiwiri, imagwirizana ndi zojambula zamatabwa a Microb, kusokoneza ndi kupulumuka kwawo ndi kubereka; Chachitatu, kuvomerezedwa kwa plasma membrane kumalepheretsa kuchotsedwa ndi michere ya michere mu thupi, zomwe zimapangitsa chidwi komanso kusintha. Mukugwiritsa ntchito zoteteza, tidzazipeza kuti ndizotheka kufooketsa nthawi. Kuphatikiza pa mphamvu ya malonda, tiyenera kuganiziranso chifukwa chomwe mabakiteriya adalimbana ndi kusungirako kwa nthawi yayitali pakuswana ndi kuwunika. , momwemonso njira zenizeni tiyenera kusintha mitundu yosiyanasiyana ya oteteza kwakanthawi.
6. Mphamvu ya Kusungidwa kwa Glaz Slurry
Pali magwero awiri akulu a CMC kulephera. Wina ndi oxidation yoyambitsidwa ndi mpweya, ndipo winayo ndi magazi a bacteria. Madzi ndi kuyimitsidwa mkaka ndi zakumwa zomwe titha kuona m'miyoyo yathu zimakhazikikanso ndi trimarization ndi cmc. Nthawi zambiri amakhala ndi alumali pafupifupi chaka chimodzi, ndipo zoyipa ndi miyezi 3-6. Chifukwa chachikulu ndikugwiritsa ntchito chomata chomata ndi ukadaulo wosungiramo zinthu zosindikizira, zimawombedwa kuti glaze iyenera kusindikizidwa ndikusungidwa. Kudzera mu fanizo 8 ndi chiwembu 9, titha kupeza kuti glaze yosungidwa ku Airteight yosungidwa imatha kukhala yokhazikika kwa nthawi yayitali popanda mpweya. Ngakhale muyeso womwe umapangitsa kuti ukhale wolimba, sukukwaniritsa zoyembekezera, koma ali ndi nthawi yayitali yosungirako. Izi zili choncho chifukwa kudzera mu glaze yosungidwa m'thumba losindikizidwa limayang'ana kukokoloka kwa mpweya ndi mabakiteriya ndikupitirira moyo wa alumali wa methyl.
7.. Zovuta za nthawi ya cmc
Kukula ndi njira yofunika kwambiri pakupanga kwa glaze. Ntchito yake yayikulu ndikupanga mayunifomu molunjika, chotsani mpweya wowonjezera ndipo ndikuwola zinthu zina, kotero kuti glaze pamwamba pakugwiritsa ntchito ma pini ndi zilema zina. Zilonda za CMC polymer zowonongeka panthawi ya mphete za mpira zimayanjanitsidwa ndipo kuchuluka kwake kumawonjezeka. Chifukwa chake, ndikofunikira kwa nthawi yayitali, koma mawonekedwe a nthawi yayitali amabweretsa ma microbial ndi kuchuluka kwa nthawi yotsika komanso kuwonjezeka kwa maola 48-72, ndibwino kugwiritsa ntchito glaze strarry. Popanga fakitale inayake, chifukwa kugwiritsa ntchito glaze ndi kochepa, tsamba losangalatsa limayendetsedwa ndi kompyuta, ndipo kusungidwa kwa glaze kumakulitsidwa kwa mphindi 30. Mfundo yayikulu ndiyo kufooketsa hydrolysis yoyambitsidwa ndi cmc yosangalatsa ndi kutentha ndi kutentha kukwera ma microorganisms kuchulukitsa kupezeka kwa magulu a methyl.
