Qosol: Codsiga Gudahahydroxypropyl methylrcelluloseHalkii laga keeni lahaa mid ka mid ah soo saarista PVC oo leh shahaadada polymerization ee sarreeya ayaa la soo saaray. Saamaynta laba nooc oo ah hydroxypropyl methylrcellellase ee ku saabsan guryaha PVC oo leh shahaadada pvidmization ee sareeya ayaa la baaray. Natiijooyinka ayaa muujinaya inay macquul tahay in lagu beddelo hyroxypropyl methyl bylule oo loo soo dejiyo mid loo soo dejiyo.
Resis-polymation-pvc-of-polymerization pvc-ka-polymation-ka ah ayaa tixraaca PVC-ka oo leh celcelis ahaan heerka polymomemization in ka badan 1,700 ama qaab-yar oo iskutallaab ah oo u dhexeeya moleekuleyaasha, oo ay yihiin kuwa pvc-ka ah ee celcelis ahaan polymomerization 2,500 [1]. Marka la barbar dhigo pvc Resin ee caadiga ah, pvc pass pvc pvc resin wuxuu leeyahay adkeysi sare, isku-dhafsi yar oo la dejiyey, iska caabin wanaagsan, iska caabin da 'ah, iska caabin da' ah, iska caabbinta daalanka iyo caabbinta. Waa bedelo caag ah oo ku habboon oo loo isticmaali karo xargaha xargaha gawaarida, fiilooyinka iyo fiilooyinka, caagayaasha caafimaadka, iwm.
Qaabka wax soo saarka ee PVC oo leh heer sare oo polymomaneration ah ayaa inta badan ka joojinta ciribtirka (3-4]. In soo saarista habka hakinta, kala sooc-firidhsan waa wakiilka kaabayaasha ah ee muhiimka ah, oo nooceeda iyo qaddarka ayaa si toos ah u saameyn doona qaabka loo yaqaan 'Qeybta' Qeybta Qeybta ', iyo Isugeynta Cabbirka Qeybta, iyo nuugista balaastikada ee PVC Resin. Nidaamyada faafinta ee caadiga ah ee loo adeegsado waa nidaamyada khamriga ee polyveryl iyo hydroxypylylylrcellellalose iyo nidaamyada kala-sooca aalkolada maskaxda ee polyvervinyl, iyo soo-saareyaasha guryaha badankood badanaa waxay adeegsadaan kan dambe [5].

4 Gudaha
Tijaabada gurigahydroxypropyl byluleOn aaladda 10aad ee imtixaanka yar ee 10aad waxay muujineysaa inay leedahay suuragalnimada in la beddelo dibedda laga keenay byroxypropyl bylulose; Natiijooyinka baaritaanka wax-ka-soo-saarku waxay muujinayaan in guryaha guryuhu ka soo baxo bylulose methy plusin, tilmaanta tayada leh ee tayada leh ee PVC Resin Resin iyo dibedda laga keenay bydroxypropyl bylulose wax macno ah ma leh. Waqtigan xaadirka ah, qiimaha unugyada guriga ee suuqa ayaa ka hooseeya tan kabitaanka unugyada laga soo dejiyo. Sidaa darteed, haddii cudurka cellulose loo isticmaalo wax soo saarka, qiimaha qalabka wax soo saarka si weyn ayaa loo dhimi karaa.
