Saamaynta hydroxypropyl methylcellulose ee sifooyinka alaabta la taaban karo!

Hydroxypropyl methylcellulose (HPMC) waxa ay leedahay sifooyin dhumuc aad u fiican waxaana loo isticmaali karaa sidii wax-iska-caabbinta wanaagsan ee shubka. Waagii hore maaddadan waxa ay ahayd wax soo saar kiimikaad ah oo dalka Shiinaha gabaabsi ku ahaa, kharashkeeduna waxa uu ahaa mid aad u sarreeya. Sababo kala duwan awgood, isticmaalkeeda ee Codsiga ee warshadaha dhismaha ee dalkayga, sannadihii la soo dhaafay, iyada oo horumarinta joogtada ah ee tignoolajiyada dahaarka derbiga dibadda, la'aanta horumarka ee technology soo saarka cellulose, iyo sifooyinka wanaagsan ee maamulaha HPMC iyo xiisaha, HPMC. ayaa si weyn loogu isticmaalay warshadaha dhismaha.

Mid: Tijaabada Ka-hortagga Kala-firdhinta:

Iska caabbinta kala firdhisku waa tilmaame farsamo oo muhiim ah oo lagu cabbiro tayada kala-soocidda. HPMC waa iskudhis biyo-milmi leh, oo sidoo kale loo yaqaan resin-biyo-milmi ama polymer-ka-biyo-ku-milmi kara. Waxay kordhisaa jadwalka isku dhafka iyada oo kordhinaysa viscosity biyo. Waa maadada polymer-ku-saleysan ee u janjeerta biyaha ku milmi karaan biyaha si ay u sameeyaan xalal ama kala firidhsan. Tijaabooyinku waxay muujinayaan in marka xaddiga wax-yaraynta biyaha ee waxtarka sare leh ee naphthalene-ku-salaysan ay korodho, ku-darka biyo-yareyaasha waxay yaraynaysaa caabbinta kala firdhisanaanta sibidhka cusub ee la isku daray. Tani waa sababta oo ah biyo-yareeyaha waxtarka sare leh ee ku salaysan naphthalene ayaa ah wax-soo-saarka. Marka biyo-dhimista lagu daro hoobiye, biyo-dhimeeyaha wuxuu ku jihaysan yahay dusha sare ee qaybaha sibidhka si dusha sare ee qaybaha sibidhka ay u helaan lacag isku mid ah. Dib-u-celinta korontadu waxay ka dhigaysaa qaybaha sibidhka Qaab-dhismeedka qulqulka ee la sameeyay waa la burburiyaa, biyaha ku jira qaab-dhismeedka ayaa la sii daayaa, taas oo keeni doonta luminta qayb ka mid ah sibidhka. Isla mar ahaantaana, waxaa la ogaaday in kororka maadada HPMC, iska caabbinta kala firdhinta ee hoobiye sibidhka cusub ee la isku daray ay sii fiicnaanayso oo sii fiicnaanayso.

Laba: sifooyinka xoogga leh ee shubka:

(1) Ku darida hydroxypropyl methylcellulose waxay leedahay saameyn gaabis muuqata oo ku saabsan isku dhafka hoobiye. Kor u kaca tirada HPMC, wakhtiga dib u dhigista hoobiye ayaa la kordhiyaa si isdaba joog ah. Marka la eego qaddarka la midka ah ee HPMC, samaynta biyaha hoostooda Wakhtiga dejinta hoobiye-haweedka hawadu way ka dheer tahay tan hawada, taas oo faa'iido u leh bamgareynta shubka biyaha ku salaysan.

(2) Hoobiyaha sibidhka ee dhawaan la isku daray ee lagu daray hydroxypropyl methylcellulose waxa uu leeyahay sifooyin isku xidhan oo wanaagsan oo aan wax dhiig-bax ah lahayn.

(3) Qadarka hydroxypropyl methylcellulose iyo baahida biyaha ee hoobiye ayaa marka hore hoos u dhacay ka dibna si cad u kordhay.

(4) Isku darka wakiilka biyaha dhimaya waxay hagaajinaysaa dhibaatada korodhka baahida biyaha ee hoobiye, laakiin qiyaasta qiyaasta waa in si macquul ah loo xakameeyaa, haddii kale biyaha hoostooda ee ka hortagga firidhsanaanta sibidhka cusub ee isku dhafan ayaa mararka qaarkood la dhimi doonaa.

(5) Ku darista hydroxypropyl methylcellulose biyaha hoostooda isku-darka shubka ah ee aan la firi karin, xakameynta qiyaasta ayaa faa'iido u leh xoogga. Tijaabadu waxay muujinaysaa in saamiga xoogga shubka biyaha ka samaysan iyo shubka hawada ka samaysan yahay 84.8%, saamayntuna si weyn baa loo barbar dhigay.
