Kubera ko imiterere ya hydroxypropyl methylcellulose isa nizindi ethers zishonga mumazi, irashobora gukoreshwa mugutwikiriye emulsiyasi hamwe nudukingirizo twinshi twa resin yogukoresha nkibikoresho bikora firime, kubyimbye, emulifier na stabilisateur, nibindi, bitanga firime yo gutwikira Kurwanya abrasion.Gufatanya hamwe no gufatana hamwe, hamwe no kunoza ubuso bwubutaka, gutuza kuri acide na base, no guhuza ibyuma byibyuma.
Kubera ko HPMC ifite gel irenze MC, irashobora kandi kurwanya indwara ya bagiteri kurusha izindi selile ya selile, bityo ikaba ishobora gukoreshwa nkigikoresho cyo kubyimba amavuta yo kwisiga.HPMC ifite ububiko bwiza bwo kubika neza kandi ikwirakwizwa neza, bityo HPMC irakwiriye cyane nkikwirakwiza muri emulsion.
Ikoreshwa rya hydroxypropyl methyl selulose mu nganda zitwikiriye nuburyo bukurikira.
1.ubukonje butandukanye HPMC iboneza irangi kwambara, kurwanya ubushyuhe bwinshi, kurwanya anti-bagiteri, gukaraba no gutuza kuri acide na base nibyiza;irashobora kandi gukoreshwa nkumurangi wamabara urimo methanol, Ethanol, propanol, inzoga ya isopropyl, Ethylene glycol, acetone, methyl etyl ketone cyangwa umubyimba wa diketone;HPMC yakozwe na emulisifike ifite ibishishwa byiza cyane;HPMC kuruta HEC na EHEC na CMC nka HPMC igira ingaruka nziza kurenza HEC na EHEC na CMC nkibara ryinshi.
2.Isimburangingo ya hydroxypropyl methyl selulose ifite imbaraga zo kurwanya indwara ya bagiteri kuruta gusimburwa gake, kandi ifite ubwiza bwimitekerereze myiza muri polyvinyl acetate.Ubundi ether ya selulose iri mububiko kubera kwangirika kwurunigi rwa selile ya selile kandi bigatuma igicucu cyacyo kigabanuka.
3.ibara risize irangi rishobora kuba amazi ya HPMC (aho imikorerexy ari 28% kugeza 32%, hydroxypropoxy ni 7% kugeza 12%), dioxymethane, toluene, paraffin, Ethanol, methanol iboneza, bizashyirwa hejuru yubusa, hamwe ibyangombwa bisabwa kandi bihindagurika.Irangi ryirangi rikuraho amarangi asanzwe ya spray, langi, emam, hamwe na est est est epoxy, epoxy amide, catisale epoxy amide, acrylates, nibindi. Irangi ryinshi rishobora gukurwaho mumasegonda make, amarangi amwe akenera 10 ~ 15min cyangwa arenga, ibi irangi ryirangi rirakwiriye cyane cyane hejuru yimbaho.
4.Irangi ryamazi ya emulsiyo irashobora kuba igizwe nibice 100 bya organic organique cyangwa organic pigment, 0.5 ~ 20 yibice byamazi ya alkyl selile cyangwa hydroxyalkyl selulose na 0.01 ~ 5 bya polyoxyethylene ether cyangwa ether ester.Kurugero, ibara riboneka mukuvanga ibice 1.5 bya HPMC, 0,05 bya polyethylene glycol alkyl phenyl ether, ibice 99.7 bya dioxyde de titanium na 0.3 byumukara wa karubone.Uruvange noneho ruvangwa nibice 100 bya 50% bya polyvinyl acetate ikomeye kugirango ubone igifuniko, kandi nta tandukaniro riri hagati ya firime yumye yumye yakozwe uyishira kumpapuro zibyibushye hanyuma ukayisiga byoroheje hamwe na brush.
