CodsigaHydroxypropyl Methyl CelluloseDaabacaadda Khadka
Khadku waxa uu ka kooban yahay midabyo, xidhidhayaal iyo walxo caawiye ah (hydroxypropyl methylcellulose), kuwaas oo la isku daray oo la duubay.
Diyaar u ah in qalin lagu sameeyo Midabka, jirka (sida caadiga ah sifooyinka rheological ee khad sida joogteynta khafiifka ah iyo dheecaanka waxaa lagu magacaabaa jirka khad) iyo waxqabadka qalajinta ayaa ah saddexda ugu muhiimsan ee khad.
Isla markiiba hydroxypropyl methylcellulose ee daabacaadda khadku waa budo cad oo aan ur lahayn, dhadhamin lahayn.
Waxay bararaysaa xal kolloidal ah oo cad ama waxoogaa daruuro ah oo biyo qabow ah. Waxay leedahay sifooyinka dhumucdi, isku-xidhka, kala firdhinta, emulsification, filim samaynta, joojinta, adsorption, gelation, dhaqdhaqaaqa dusha sare, haynta biyaha iyo koloid ilaalinta. door muhiim ah ayuu ka qaataa.

Hydroxypropyl methylcellulose waxay leedahay saddex muuqaal oo kala ah 100,000, 150,000, iyo 200,000. Viscosity waa sifada socodka dareeraha khad.
Tusiyaha cadadka iska caabinta (ama khilaaf gudaha ah) dhaqdhaqaaqa Inta lagu jiro habka daabacaadda ka-dhaafka ah, viscosity gaar ah ayaa lagama maarmaan u ah si loo ilaaliyo wareejinta khadka si caadi ah.
Waa shuruudaha ugu muhiimsan ee dhalmada iyo wareejinta, sidoo kale waa shuruud muhiim u ah go'aaminta xawliga, caddaynta iyo dhalaalka daabacaadda. Viscosity khad
Haddii ay aad u weyn tahay, way adkaan doontaa in la wareejiyo oo la wareejiyo, si qadarka khad ee qaabka uu u noqdo mid aan ku filnayn, taas oo keenta qaawanaanta sawirada iyo qoraalka si ay u sameeyaan qaab. Sidoo kale, viscosity
Haddii ay aad u weyn tahay, sidoo kale way sahlan tahay in la keeno warqadda in ay bursanto oo budo ah, ama ay keento dillaaca xaashida daabacan. Laakiin haddii viscosity uu aad u yar yahay, way fududahay in la soo saaro
Sabeyn iyo wasakh, waxay keeni doontaa emulsification khad xaaladaha daran, haddii aysan ilaalin karin gudbinta iyo kala iibsiga caadiga ah, iyo si tartiib tartiib ah khad
Qaybaha midabku waxay ku ururaan rollers, saxannada daabacaadda iyo bustayaal, iyo marka ururintu gaadho heer go'an, waxay keeni doontaa xoqid.

Hydroxypropyl methyl cellulosewuxuu leeyahay dhejis wanaagsan, isaga oo ka fogaanaya ku dhejinta khad inta lagu jiro habka daabacaadda
Uma dhigma waxqabadka iyo shuruudaha daabacaadda substrate-ka, taasoo keentay budada warqadda, lint, daabacaadda khad liidata, daabacaadda
Guuldarrooyinka daabacaadda sida taarikada wasakhaysan.
3
Hydroxypropyl methylcellulose wuxuu leeyahay thixotropy wanaagsan, isaga oo iska ilaalinaya thixotropy khad inta lagu jiro habka daabacaadda
Daabacaada guul darrooyinka sida "qulqulka khad liidata", wareejinta khad aan sinnayn, iyo balaarinta dhibco ay sababto xumaantu.
4
Hydroxypropyl methylcellulose waxay leedahay adhesion aad u sarreeya, habka daabacaadda offset, xoogga madow ee khad ma aha oo kaliya mid toos ah.
Waxay la xiriirtaa saameynta daabacaadda iyo tayada alaabta daabacan, sidoo kale waxay si dhow ula xiriirtaa qadarka khad halkii cutubba. Haddii aad doorato
Isticmaalka khadyada leh awoodda midabaynta xooggan waxay cuni doontaa khad ka yar kuwa midabkoodu daciifka yahay, natiijooyin daabacaad fiicana waa la heli karaa.
5
Hydroxypropyl methylcellulosewaxa uu leeyahay dareere aad u fiican, khad dareere ah oo ku habboon, iyo sinnaanta isha khadka
Waxay leedahay karti wax-is-qurxineed oo wanaagsan iyo karti wax-is-qurxineed oo wanaagsan; wareejinta iyo wareejinta inta u dhaxaysa rollers-ka ama inta u dhaxaysa saxanka daabacaadda iyo buste sidoo kale waa wanaagsan tahay;
Lakabka khadku waa lebis; Filimka khad daabacan ayaa siman oo siman. Haddii dheecaanku aad u yar yahay, way fududahay in la keeno dheecaan khad oo liita; Qaybinta lakabka khad ee aan sinnayn, iwm.
ifafaale, oogada filimka khad daabacan ayaa sidoo kale ka muuqan doona doogyo. Marka dheecaanku aad u weyn yahay, lakabka khafiifka ah ee khafiifka ah waa sahlan tahay inuu keeno balaadhinta dhibcaha, daabacaadda
Midabku ma xoog badna. Habka mitirka socodka ayaa caadi ahaan la isticmaalaa.
