HPMC loo isticmaalo inWall Putty/Skim Coat

HPMC waxa loo qaybin karaa: heerka dhismaha, heerka cuntada iyo darajada caafimaadka iyadoo loo eegayo isticmaalka. HaddaShiinaha is heerka dhismaha inta badan, fasalka dhismaha,darbiga derbiga/Skim Coat qiyaastajaakad jilicsan budada aad bay u weyn tahay. Budada HPMC iyo tiro badan oo ah maaddooyinka kale ee budada ah, oo si buuxda loogu qaso blender, ka dibna ku dar biyo si ay u milaan, wakhtigan HPMC way milmi kartaa, laakiin ma aha aglomerate, sababtoo ah gees kasta oo yar, wax yar oo budada HPMC ah, biyaha ayaa isla markiiba milmi doona.Skim CoatShirkadda soo saarista budada iyo hoobiye ayaa aad u isticmaala habkan oo kale. Hydroxypropyl methyl cellulose (HPMC) waxaa loo isticmaalaa sidii dhumuc iyo wakiilka biyaha ee hoobiye putty.

Heerkulka jel ee HPMC wuxuu la xiriiraa maadada methoxyl, hoos u dhaca maadada methoxylhoos, heerkulka jelku wuu sarreeyaa up. HPMC biyaha qabow nooca xal degdeg ah ka dib daawaynta dusha glioxal, ku rid biyo qabow si degdeg ah u kala firdhiyey, laakiin aan runtii milmin, viscosity kor, waa la kala diri. The thermosoluble HPMC nooca dusha laguma daawayn glycoxal. Qadarka glycoxal waa weyn yahay, kala firdhisyadu waa dhakhso, laakiin maqaarku waa gaabis, qadarku waa yar yahay, liddi ku ah. HPMC waxaa loo qaybin karaa isla markiiba iyo kulaylka milmay, alaabta degdega ah, in biyo qabow si degdeg ah u kala firdhiyey, la waayay biyaha, wakhtigan dareere ma laha viscosity, sababtoo ah HPMC kaliya ku kala firdhiyey biyaha, ma jiraan wax kala diri dhab ah. Qiyaastii 2 daqiiqo, viscosity ee dareeraha ayaa si tartiib tartiib ah u kordhaya, samaynta kolloid viscos ah oo hufan. Alaabooyinka kulaylka leh, agglomeration biyo qabow, waxay ku jiri karaan biyo kulul, si deg deg ah u kala firdhiyaan, baaba'aan biyo kulul, ilaa heerkulku hoos u dhaco heerkul gaar ah, viscosity si tartiib tartiib ah ayaa u muuqda, ilaa formation of kolloid viscous hufan. Nooca kulaylka lagu milmo waxa kaliya oo lagu isticmaali karaaSkim Coat iyo hoobiye, ee xabagta dareeraha ah iyo daahan, waxay u muuqan karaan ifafaale agglomeration, lama isticmaali karo. Moodeelka kala dirida degdega ah, baaxadda arjigu waa xoogaa ka ballaaran, gudahaSkim Coatbudada iyo hoobiye, iyo koollada dareeraha ah iyo daahan, dhammaan waa la isticmaali karaa, ha haysan waxa mamnuuc ah.

Habka xalinta wax soo saarka ee HPMC, waxaa laga sameeyaa toluene, dareeraha aalkolada isopropyl, haddii dhaqidda ma aha mid aad u wanaagsan, waxaa jiri doona qaar ka mid ah dhadhan haraaga ah. codsigaSkim Coat  budada: shuruudu waa liidata, viscosity 100000, waxaa muhiim ah in la ilaaliyo biyaha si loogu dhawaado. Codsiga hoobiye: Shuruudaha sare, shuruudaha viscosity-sare, 150000 si uu u fiicnaado. Codsiga xabagta: baahida loo qabo alaabta degdega ah, viscosity sare. HPMC ee codsiga dhabta ah ee qadarka, by jawiga cimilada, heerkulka, tayada calcium cawl deegaanka,Skim Coat formula iyo "shuruudaha macaamiisha ee tayada" ee kala duwan, oo waxaa jira kala duwanaansho. Hydroxypropyl methyl cellulose (HPMC) ee viscosity-Skim Coatbudo waa100000, Qaar ka mid ah kuwa ka dheer shuruudaha hoobiye, waxay rabaan 150 kun oo awood ah inay isticmaalaan. Waxaa intaa dheer, doorka ugu muhiimsan ee HPMC waa in la ilaaliyo biyaha, oo ay ku xigto dhumucdi. GudahaSkim Coat, ilaa iyo inta haynta biyuhu ay wanaagsan yihiin, viscosity-ku wuu hooseeyaa (7-80000), sidoo kale waa suurtogal, dabcan, viscosity waa ka weyn yahay, haynta biyaha qaraabada ah ayaa ka sii fiican, marka maqaarku ka badan yahay 100000, viscosity ee haysashada biyuhu ma badna; Waxa ku jira Hydroxypropyl waa sarreeyaa, haynta biyaha ayaa guud ahaan ka wanaagsan. Viscosity, haynta biyaha, ilaa xad ka wanaagsan, iyo viscosity, ee hoobiye sibidhka ayaa si fiican loo isticmaalo.

HPMC gudahaSkim Coat, dhumucdiisuna, haynta biyaha iyo dhismaha saddex hawlood. Aan ka qayb qaadan wax falcelin ah. Sababta xumbada waxay noqon kartaa biyo aad u badan, sidoo kale waxaa laga yaabaa in hoosta aan qallajin, dusha sare ee lakabka xoqida, sidoo kale si sahlan loo xumbo. HPMC ee saamaynta dhumuc eeSkim Coat: cellulose waxa lagu dhumucdi karaa ganaax, si uu xalku u ahaado mid la mid ah kor iyo hoos doorka ka soo laadlaadda qulqulka. Saamaynta haynta biyaha ee HPMC eeSkim Coat: sameeSkim Coat si tartiib ah u qallaji, falcelin kalsiyum cawl cawlan caawiye hoos ficilka biyaha. HPMC gudahaSkim Coat doorka dhismaha: saliidda cellulose, samayn kartaaSkim Coat wuxuu leeyahay dhismo wanaagsan. HPMC kama qaybqaadato fal-celin kiimikaad, laakiin kaliya waxay ciyaartaa door taageero.

darbiga derbiga/Skim Coat budada iyo tayada ugu weyn ee kalsiyumka dambaska ayaa leh xiriir weyn, HPMCna ma lahan xiriir weyn. Kaalshiyamka hoose ee kalsiyumka cawl iyo saamiga aan habboonayn ee CaO iyo Ca(OH)2 ee kaalshiyam cawl ayaa sababi doona daadinta budada. Haddii uu jiro xiriir yar oo lala yeesho HPMC, markaa waa HPMC biyo-hayn liidata, waxay sidoo kale keeni doontaa budada,Skim Coat iyo biyaha, derbiga, waa falcelin kiimikaad, sababtoo ah jiilka walxaha cusub, derbigaSkim Coat derbiga hoos uga soo daa, oo budo noqda, ka dibna isticmaal, ha isticmaalin khadka, sababtoo ah waxay samaysay walax cusub (calcium carbonate). Qaybaha ugu muhiimsan ee budada calcium cawl waa: Ca (OH) 2, CaO iyo qadar yar oo CaCO3 isku dar ah, CaO+H2O=Ca(OH)2 - Ca(OH)2+CO2=CaCO3↓+H2O calcium cawl biyaha iyo hawada hoos ficil CO2, formation of calcium carbonate, iyo HPMC biyo kaliya, kaalshiyam cawl kalsiyum falcelin ka fiican, iyada u gaar ah ma ka qayb falcelin kasta.
