01. Hydroxyethyl cellulose
Monga osakhala ocheperako, hydroxethyl cellose sikuti ndi ntchito zokhazokha zoyimitsa, kufalitsa, kulumikizana, kupanga mafilimu, komanso ali ndi zinthu zotsatirazi:
1. Hec imasungunuka m'madzi otentha kapena ozizira, ndipo osayendetsa kutentha kwambiri kapena kuwira, kotero kuti ili ndi mawonekedwe osiyanasiyana komanso owoneka bwino;
2. Poyerekeza ndi methyl cellose ndi hydroxypropyl methyl celyilose, kuthekera kwa hec ndiye choyipa kwambiri, koma cololaid compaid imakhala ndi mphamvu yolimba.
3. Kuchuluka kwa madzi ndikokwera kwambiri ngati kwa methyl cellulose, ndipo ili ndi njira yabwino kwambiri.
Kusamala mukamagwiritsa ntchito:
Popeza ma valroxyethyl opaleshoni ali ndi ufa kapena ma cellulose olimba, ndizosavuta kusamalira ndikusungunuka m'madzi malinga ngati zotsatirazi zikuchitika.
1. Asanayambe ndi mutawonjezera hydroththyl cellulose, ziyenera kukhala zikusunthidwa mosalekeza mpaka yankho lawonekeratu.
2. Uyenera kukhala wodetsedwa kusakaniza mbiya yosakaniza pang'onopang'ono. Osawonjezera mwachindunji ma cellulose omwe apangidwa mu zotupa kapena mipira mu mbiya yosakanikirana kwambiri kapena mwachindunji.
3. Kutentha kwamadzi ndi mtengo wamtengo wa madzi zimakhala ndi ubale wofunikira ndi kusungunuka kwa hydroxethyl cellulose, chidwi chachikulu chiyenera kulipiridwa kwa icho.
4. Osambitsani zinthu zina za alkaline kuti chisakanizo chisanachitike ma hydroxethyl cellulose apa ufa amawazidwa ndi madzi. Kukweza mtengo wa pH mutatha kutentha kumathandiza pakuwonongeka.
Gwiritsani ntchito hec:
1.
2. Imagwiritsidwa ntchito ngati yojambula m'makampani opanga malemba, kugwirizanitsa, kukulitsa, kukhazikika, kukhazikika, kukhazikika ndi magawo ena a malonda amalekitala.
3. Kugwiritsidwa ntchito ngati thicker ndi kuchepa kwa madzi okwera madzi ndi kumaliza madzi, ndipo ali ndi kukula kwamphamvu m'madzi amchere. Itha kugwiritsidwanso ntchito ngati madzi otayitsa mafuta a mafuta abwino. Itha kukhala yolumikizidwa ndi ma ionyvaler zitsulo kuti apange ma gels.
5. Izi zimagwiritsidwa ntchito ngati wobalalitsa madzi obwera chifukwa cha madzi, polystyrene ndi polyvinyl chloride mu mafuta ogwiritsira ntchito mafuta. Itha kugwiritsidwanso ntchito ngati emulsion trickener pa utoto wamagetsi, chinyezi chazitsulo zamagetsi zamagetsi, kuphatikiza kwa simenti kumalepheretse ntchito yomanga. Kukopa ndi zomata zomata zomata zam'masuthi. Amagwiritsidwanso ntchito kwambiri posindikiza ndi kupaka utoto, pepala, mankhwala, ukhondo, ndudu, ndudu, mankhwala ophera tizilombo.
02.hydroxypypyl methyl cellulose
1. Makampani okumba: Monga thiccener, wobayira komanso wokhazikika m'makampani okutira, amakhala ndi kuthekera kwa madzi kapena okhazikika. ngati utoto.
2. Kupanga kwa deramic: kugwiritsidwa ntchito kwambiri ngati chomangira popanga zinthu za ceramic.
3. Ena: Chomera ichi chimagwiritsidwanso ntchito kwambiri m'chikopa, mapepala ogulitsa mapepala, zipatso ndi mankhwala osokoneza bongo komanso mafakitale, etc.
4. Makina osindikizira: kukhala tlicker, wobalalitsa ndi kukhazikika m'makampani a inki, ali ndi kuthekera kwa madzi kapena okhazikika.
5. Pulasitiki: Wogwiritsidwa ntchito ngati womasulidwa wotulutsa, sofener, mafuta, etc.
6. Polyvinyl chloride: Amagwiritsidwa ntchito ngati wobalalitsa polyvinyl chloride, ndipo ndiye wamkulu wothandizira wothandizira pokonzekera pvc poyimitsidwa polymerization.
7. Makampani omanga: Monga wothandizirana ndi madzi komanso wobwezera matope a simenti, matope ali ndi kupatulidwa. Zogwiritsidwa ntchito ngati chomangira pa phala lopaka, gypsum, putty ufa kapena zinthu zina zomanga kuti zikulepheretse kufalikira ndi nthawi yayitali. Amagwiritsidwa ntchito ngati phala la matayala, zokongoletsa pulasitiki, ngati phala, ndipo limathanso kuchepetsa kuchuluka kwa simenti. Kusunga kwamadzi kwa hydroxpyl methylcellulose hpmc kungalepheretse kuwonongeka chifukwa chopukutira mwachangu pambuyo pakugwiritsa ntchito, ndikuwonjezera mphamvu pambuyo polimbana.
8. Makampani ogulitsa mankhwala: Zipangizo zokutira; Zipangizo za makanema; kuchuluka kwa polima polymer kuti mukonzekere kutukuka; okhazikika; Kuyimilira; ma piritsi a piritsi; tackifiers.
Chilengedwe:
1. Maonekedwe: oyera kapena oyera-oyera.
2. Kukula kwa tinthu; Kuchuluka kwa mauna 100 ndi akulu kuposa 98,5%; Mlingo wa Mesh Unge ndi 100%. Kukula kwa mawonekedwe apadera ndi 40 ~ 60 mesh.
3. Kutentha kwa kada: 280-300 ℃
4.
5. Kutentha kosiyanitsa: 190-200 ℃
6. Matendawa: 2% am'madzi am'madzi ndi 42-56dy / cm.
7. Kusungunuka: kusungunuka m'madzi ndi ena mabedi, monga gawo loyenerera la ethanol / madzi, propyal / madzi, zosintha za etc. Kuwonekera kwambiri komanso kusisita. Makina osiyanasiyana a zinthu amakhala ndi kutentha kosiyanasiyana, komanso kusungunuka kumasintha ndi mafayilo. Kutsitsa mamasukidwe, chachikulucho chosungunuka. Makina osiyanasiyana a hpmc ali ndi zida zosiyanasiyana. Kuwonongeka kwa HPMC m'madzi sikukhudzidwa ndi mtengo wa pH.
