(Hydroxypropyl) methyl cellulose | CAS 9004-65-3

(Hydroxypropyl) methyl cellulose, oo sidoo kale loo yaqaano soo gaabinta HPMC ama nambarkeeda CAS 9004-65-3, waa ether cellulose ah oo ka soo jeeda cellulose dabiiciga ah. Waa polymer semi-synthetic ah oo si weyn loogu isticmaalo warshado kala duwan iyadoo ay ugu wacan tahay sifooyinkeeda gaarka ah iyo kala duwanaanshiyaha. Halkan si dhow u eeg xaruntan:

Dhismaha iyo Guryaha:
1 Qaab dhismeedka: HPMC waxa lagu farsameeyaa habaynta kiimikaad ee cellulose, halkaas oo labada methyl (-CH3) iyo hydroxypropyl (-CH2CHOHCH3) kooxaha lagu soo bandhigo lafta dhabarka cellulose.
2 Degree Beddelka (DS): Heerka beddelka waxa loola jeedaa celceliska tirada kooxaha beddelka ah ee unugga gulukoosta ee silsiladda cellulose. Waxay go'aamisaa sifooyinka HPMC, sida milanka, viscosity, iyo kartida samaynta filimada.
3 Guryaha: HPMC waxa ay soo bandhigtaa sifooyin ay ka mid yihiin dhumucdi, haynta biyaha, samaynta filimada, iyo dhaqdhaqaaqa dusha sare. Guryaha waxaa lagu hagaajin karaa iyada oo la xakameynayo DS inta lagu jiro isku-dhafka.

Wax soo saar:
1.Cellulose Sourcing: Cellulose, alaabta ceeriin aasaasiga ah ee HPMC, waxaa laga helay ilo la cusboonaysiin karo sida saxarka alwaax ama suuf.
Etherification: Cellulose waxay martaa etherification, halkaas oo lagu falceliyo propylene oxide si loo soo bandhigo kooxaha hydroxypropyl ka dibna methyl chloride si loogu daro kooxaha methyl.
2.Nadiifinta: cellulose-ka la beddelay ayaa la nadiifiyaa si looga saaro wasakhda iyo alaabada, taasoo keentay badeecada ugu dambeysa ee HPMC.
Codsiyada:
3.Construction Industry: HPMC waxaa si weyn loogu isticmaalaa in qalabka dhismaha sida hoobiye ku salaysan sibidhka, balastarrada, iyo xabagta dhoobada si loo hagaajiyo shaqada, haynta biyaha, iyo adhesion.
4.Pharmaceuticals: Waxay u adeegtaa sidii binder, dhumuc weyn, filim hore, iyo xasiliye qaabaynta dawooyinka oo ay ku jiraan kiniiniyada, kaabsalka, xalalka indhaha, iyo kiriimyada jirka la mariyo.
5. Warshadaha Cuntada: HPMC waxay u shaqeysaa sidii dhumuc, dejiye, iyo emulsifier ee cuntooyinka kala duwan sida suugada, dhaymada, jalaatada, iyo alaabta la dubay.
6.Cosmetics and Personal Care: Waxyaabaha la isku qurxiyo iyo alaabta daryeelka shakhsi ahaaneed, HPMC waxa loo isticmaalaa dhumuc ahaan, wakiilka hakinta, filim hore, iyo qoyaan kiriimyada, looshannada, shaambooyinka, iyo jelka.
7.Paints iyo Coatings: Waxay wanaajisaa viscosity, caabbinta sag, iyo sifooyinka sameynta filimka ee rinjiyada biyaha ku salaysan, dhejisyada, iyo dahaarka.
Gabagabo:
(Hydroxypropyl) methyl cellulose, oo leh noocyo kala duwan oo codsiyo ah iyo sifooyin faa'iido leh, ayaa ah shay muhiim u ah alaabooyin badan oo warshado iyo ganacsi ah. Doorkeeda kor u qaadida waxqabadka, xasiloonida, iyo shaqaynta qaabab kala duwan ayaa ka dhigaysa mid aan looga maarmin qaybaha kala duwan. Maaddaama warshaduhu ay sii wadaan hal-abuurnimada, baahida loo qabo HPMC ayaa la filayaa inay sii socoto, taasoo horseedaysa horumar dheeraad ah oo ku saabsan hababka wax-soo-saarka iyo codsiyada.
