Hydroxypropyl Methyl Cellulose (HPMC) ugu Fiican ee loo Isticmaalo Soo-saaraha iyo Warshadda Rinjiga ee Biyaha ku salaysan

Hydroxypropyl Methyl Cellulose (HPMC) Loo Isticmaalo Rinjiga Ku Salaysan Biyaha Sawirka La Soo Bandhigay

Hydroxypropyl Methyl Cellulose (HPMC) Waxaa loo isticmaalaa Rinjiga ku salaysan biyaha

Rinjiga/dahaarka biyaha ku salaysan waxaa mudnaanta la siiyaa iyadoo la isticmaalayo colophony, ama saliid, ama emulsion, ku dar qaar ka mid ah kaaliyeyaal u dhigma, oo leh milmiye dabiici ah ama qaab-dhismeed biyo ah oo noqda dareere dhegdheg leh. Rinjiga biyaha ku salaysan ama dahaarka leh waxqabad wanaagsan ayaa sidoo kale leh waxqabad shaqo oo heer sare ah, awood dabool wanaagsan, dhegdheg xooggan oo filimka ah, haynta biyaha oo wanaagsan iyo astaamo kale; Cellulose ether waa walaxda ugu habboon ee ceeriin ah si loo bixiyo sifooyinkan.

Waxqabadkayaga ilaalinta biyaha ee cellulose ether ee dahaarka latex, gaar ahaan dahaarka sare ee PVA wuxuu bixiyaa waxqabad dahaar oo aad u fiican, dahaarka saxarka qaro weyn, ma soo saari doono flocculation; Saamayntiisa dhumucda sare waxay yareyn kartaa qiyaasta, waxay hagaajin kartaa dhaqaalaha qaacidada, waxayna hagaajin kartaa joojinta nidaamka dahaarka. Sifooyinka rheological ee aadka u fiican ee dahaarka, waxay ku jiri karaan xaalad aan degganayn, waxay ilaalin karaan xaaladda dhumucda ugu fiican ee dahaarka; Xaaladda la tuuray, oo leh dareere aad u fiican, mana firdhi doono; Dahaarka iyo dahaarka duubka, oo si fudud loogu faafin karo substrate-ka, qaab dhismeed ku habboon; Marka dahaarka la dhammeeyo, dheellitirka nidaamku isla markiiba wuu soo kaban doonaa, dahaarka isla markiiba wuxuu soo saari doonaa socod.

Dunida aadka u firfircoon ee rinjiyeynta latex-ka ku salaysan biyaha, mid ka mid ah waxyaabaha aadka muhiimka u ah waa Hydroxy Propyl Methyl Cellulose.(HPMC)Marka laga reebo inuu yahay dhumuc-saare aad waxtar u leh, noocan lagu daro wuxuu sidoo kale bixiyaa sifooyin kale oo badan oo faa'iido leh, sida awoodda burushka, iska caabbinta hoos u dhaca, emulsification, awoodda joojinta, iwm, iyadoo bixinaysa iswaafajin midab oo aad u wanaagsan,sidoo kaleka dhigista noocan dhumuc-dhegista mid aad caan uga ah soosaarayaasha rinjiga badan ee adduunka.

Waxaa loo isticmaalaa rinjiga biyaha ku salaysan. Waxay muujinaysaa saameyntiisa dhumucda sare ee aadka u fiican,iyoSifooyinka rheological, kala firdhinta iyo milmida. Waxay leedahay xasillooni bayooloji oo wanaagsan, waxay siisaa waqti ku filan kaydinta rinjiga. Si wax ku ool ah ayay uga hortagtaa midabyada iyo buuxinta.
