Kusanthula pazifukwa zomwe zimapangitsa njira zosiyanasiyana zowonjezera za hydroxethyl cellulose pa utoto wa matope

Hydroxyethyl cellulose (hec) ndi yodziwika bwino komanso yollsifier, yomwe imagwiritsidwa ntchito kwambiri mu utoto wa lamba. Ntchito yake yayikulu ndikuwonjezera mapangidwe a utoto, sinthani chinsinsi, kuwonjezera kuyimitsidwa ndi kukhazikika kwa zokutira, etc.

1. Kupatula njira ya hydroxyethyl cellulose
Popanga utoto wa latex, nthawi zambiri pamakhala njira zitatu zowonjezera cellulose: njira yokhudza mwachindunji, kupezeka njira yowonjezera, njira yothetsera chizolowezi.

Kusankha mwachindunji: Onjezani hydroxyethyl cellulose kupita ku zinthu zopaka za landx utoto, nthawi zambiri pambuyo pa emulsion kapena utoto umabalalika, ndikuyambitsa. Njirayi ndiyosavuta komanso yosavuta, koma imatha kubweretsa chisokonezo chosakwanira cha hydroxethyl cellulose, yomwe imakhudza za utoto wa utoto.

Kubalalika Kowonjezera: Kubalalitsa hydroxyethyl cellulose ndi gawo la madzi kapena solvent kaye, kenako ndikuwonjezera pa utoto wa mapepala. Njirayi imathandizira kufalitsa ma hydroxyethyl cellulose ndikupewa mapangidwe ake a ma agglomerates, potero akuwongolera mawonekedwe ndi kukhazikika kwa utoto.

Njira Yowonongeka Yosasinthika: Sungunulani hydroxyethyl cellulose yokhala ndi madzi oyenera kapena solvent patsogolo kuti apange yankho la yunifolomu, kenako ndikuwonjezera utoto wa lankx. Njirayi ingawonetsetse kuti ma celrouthyl amasungunuka kwambiri m'dongosolo, omwe amathandizira kukonza chiwuno ndi thixotropy ya utoto, kotero kuti ali ndi vuto la utoto komanso madzi.

2. Zotsatira za njira zosiyanasiyana zowonjezera pa magwiridwe antchito a penti ya latex

2.1 rhelogy ndi thixotropy
Rhelogy amatanthauza katundu wa chinthu choyenda pansi pa mphamvu yakunja, ndipo thixotropy amatanthauza malowa omwe akuwoneka kuti akusintha. Mu utoto wa mochedwax, hydroxyethyl cellulose monga kukula kwambiri kumatha kusintha zomwe zimapangitsa kuti azitha kubereka komanso thixotropy.

Njira yodziwitsira mwachindunji: chifukwa chosasinthika cha hydroxethyl cellulose, mawonekedwe a utoto amatha kukhala osagwirizana, ndipo ndizosavuta kukhala ndi mavuto monga kusowa kwamafuta osauka komanso zovuta. Kuphatikiza apo, kuwonjeza mwachindunji hydroxyethyl cellulose ingapangitse ma agglomerates akuluakulu, chifukwa cha chiphuphu chosakhazikika cha utoto panthawi yogwiritsa ntchito.

Kubalalitsa njira: kudzera pakubalalitsa, hydroxyethyl cellulose amatha kubalalitsidwa bwino mu utoto wa matope a latex, potero akuwonjezera ufa wa utoto ndi kukulitsa thixotropy. Njirayi imatha kusintha zinthu moyenera za chimbudzi, kuti zokutidwazo zimakhala ndi madzi abwino komanso zokutira zabwino panthawi yofunsira.

Njira Yofalitsira Yosatha: Pambuyo poletsa hydroxethyl cellulose kuti apange njira yothetsera yunifolomu, ndikuwonjezera pa utoto wa mochedwa Izi zimapangitsa chiwuke ndi thixotropy ya kuchuluka kwa zogwirizana ndi zotsatira zabwino, makamaka akamatonga, zimakhala ndi mawonekedwe abwino komanso osalala.

2.2 kukhazikika kwa zokutira
Kukhazikika kwa zokutira kumatanthawuza kuthekera kwake kukhala fanizo, osasunthika, komanso osakhala mpweya panthawi yosungirako ndikugwiritsa ntchito. Hydroxyethyl cellulose mu utoto wa latx imalepheretsa kukhazikika kwa utoto ndi mafilimu omwe mwakulitsa ma visc.

Kutengera mwachindunji Kupanga kwa agglomerates sikungochepetsa kukhazikika kwa chikuto, komanso kungayambitse mpweya wa utoto ndi mafayilo osungirako, akukhudza momwe akugwirira ntchito.

Kubalalika Kowonjezera: Mwa kufalikira kwa hydroththyl cellulose, kumatha kutsimikiziridwa kuti kumagawidwa kwambiri pakukutira mokutidwa, potero kumawonjezera kukhazikika kwa chimbudzi. Kubalalitsa kwabwino kumatha kulepheretsa kuwonongeka kwa masamba ndi mafakitale, kuonetsetsa kuti zokutirayo zimakhazikika pakapita nthawi yosungirako nthawi yayitali.

Njira Yowonongeka Yosatha: Njira yothetsera chisanachitike ingathe kuwonetsetsa kuti ma celrouthyl cellulose imasungunuka kwathunthu ndikupewera kupezeka kwa kusokonekera, kotero kumatha kusintha kwambiri kukhazikika kwa chimbudzi. Kuphimba sikunakhale kovuta kapena kusuntha panthawi yosungirako, kuonetsetsa kuti pali kufanana komanso kukhazikika pogwiritsa ntchito.

2.3 Kupanga Magwiridwe antchito
Kuchita zomanga kumaphatikizapo kutsika, kutsatira komanso kuthamanga kwa chitombi. Volroxyathyl cellulose imatha kugwira ntchito yomanga yomanga ndikuwongolera madzi, kukulitsa thixotropy ndikuwonjezera nthawi yotseguka.

Njira yodziwitsira mwachindunji: chifukwa chosungunuka osauka, zokutira zimatha kuyambitsa zojambula za waya kapena zikwangwani pomanga, zimakhudza kufanana ndi zokutira.

Kufalitsa njira: Powonjezera hydroxyethyl cellulose mutabala, madzi ofunda ndi ovala bwino amatha kukhala bwino, kupanga njira yomangayi yosalala. Kuphatikiza apo, kubalalika kwa ma cellose cellulose kumathandizanso kukulitsa chipembedzocho chophimba, kupangitsa kuti likhale losavuta kuti limeze pamwamba pa gawo la gawo lapansi pakutsuka.

Mfundo ya Ochenjera: Njira yolandirira imathandizira hydroththyl cellulose kuti isungunuke, kupewa zofunda, ndipo zimatha kukula bwino, ndipo zimatha kukula bwino, ndikusintha magwiridwe antchito okutira.

Njira yowonjezera ya hydroxyethyl cellulose imakhudza kwambiri utoto wa latex. Njira yodziwikiratu ndiyosavuta kugwira ntchito, koma imatha kuyambitsa kupezeka kwa ma hydroxyethyl cellulose, ndikukhudza Rhelogy, kukhazikika komanso kukhazikika ndi ntchito yomanga; Kubalalitsa kowonjezera kuphatikiza njira yosinthira ma hydroxyethyl cellulose yobalalitsidwa kwathunthu kapena kusungunuka, potengera chivundikiro, kukhazikika komanso kulimbikira kwa zokutira. Ponseponse, njira yolenderayo imatha kupereka magwiridwe antchito abwino kwambiri, makamaka pankhani ya rheology, kukhazikika komanso zolimbitsa thupi. Malinga ndi zosowa zosiyanasiyana zopanga komanso zofunika kugwiritsa ntchito, kusankha njira yoyenera kungapangire gawo la hydroxethyl cellulose mu utoto wa mochedwa.
