Hydroxypropyl Methylcellulose oo ah wakiillo kala soocid ah, alaabada la helay waxay leeyihiin walxo qaabaysan oo dabacsan, cufnaan muuqata oo ku habboon iyo waxqabad farsameed oo heer sare ah. Si kastaba ha ahaatee, isticmaalka Hydroxypropyl Methylcellulose oo keliya ayaa gacan ka geysan kara isbeddel wanaagsan oo resin ah. Waxqabadka guud ee resinku waa mid liita. Isticmaalka isku-dhafka ah ee hydroxypropyl methylcellulose iyo dhowr heer oo alkolo ah oo kala duwan oo polyvinyl aalkolo ah ayaa ka dhigi kara waxqabadka badeecadaha mid ka wanaagsan, tayada si fudud loo xakamayn karo isla markaana waxay yareyn kartaa kharashka. Wakiilka kala firdhinaya waa qodobka ugu weyn ee saameeya qaabka walxaha resin polyvinyl chloride. Inta uu yar yahay xiisadda dusha sare ee xalka biyaha ee wakiilada kala firdhiya guud iyo xiisadda isku-dhafka ah ee leh monomer-ka vinyl chloride, ayaa dhibcaha VCM-ga si fiican loo kala firdhin karaa. Sidaas darteed dhexroorka walxaha resin PVC wuu yaraan doonaa. Awoodda ilaalinta ee wakiilka kala firdhiya ayaa sii kordheysa walxaha resin PVC ee la helay iyo daloolka yar. Isku-dhafka isku-dhafka ah sidoo kale waa mid aad u adag, sidaa darteed way fududahay in la sameeyo resin.
Tusaale ahaan, nidaamka kala firdhinta isku-dhafka ah ee PVA iyo HPC, heerka sare ee alcoholism-ka ee PVA, ayaa sii weynaan doona xiisadda dusha sare ee xalka biyaha iyo awoodda ilaalinta oo sii xoogaysan doonta, halka fiirsashada gaarka ah ee hydroxypropyl methylcellulose ay leedahay saameyn kala firdhis wanaagsan. Sidaa darteed, isticmaalka PVA oo leh heer sare oo alcoholism ah oo ah heerka ugu horreeya.
wakiilka kala firdhiya, iyo isku-darka a
xaddi gaar ah oo hydroxypropyl methylcellulose ah
Maadaama uu yahay wakiilka kala firdhiya ee polymerization-ka joojinta, way fududahay in la diyaariyo resin PVC kaas oo buuxin kara shuruudaha qaab-dhismeedka walxaha. Tusaale ahaan, nidaamka kala firdhinta isku-dhafka ah ee PVA iyo HPC, heerka sare ee alkololysis ee PVA, ayaa sii weynaan doona xiisadda dusha sare ee xalka biyaha iyo awoodda ilaalinta oo sii xoogaysan doonta, halka fiirsashada gaarka ah ee hydroxypropyl methylcellulose ay leedahay saameyn kala firdhis wanaagsan.
