Sida loo isticmaalo hydroxyethyl cellulose rinjiga latex
1. Hydroxyethyl cellulose waxaa loo isticmaalaa sameynta boorashka: Maadaama hydroxyethyl cellulose aysan si fudud ugu milmin dareeraha dabiiciga ah, qaar ka mid ah dareeraha dabiiciga ah ayaa loo isticmaali karaa diyaarinta boorashka. Biyaha barafka sidoo kale waa dareere liita, sidaa darteed biyaha barafka waxaa badanaa lala isticmaalaa dareerayaasha dabiiciga ah si loogu diyaariyo boorashka. hydroxyethyl cellulose oo u eg Boorashka ayaa si toos ah loogu dari karaa rinjiga latex. Hydroxyethyl cellulose si buuxda ayaa loogu qooyay boorashka. Marka lagu daro rinjiga, si dhakhso ah ayuu u milmaa wuxuuna u shaqeeyaa sidii dhumuc weyn. Ka dib marka lagu daro, sii wad walaaq ilaa hydroxyethyl cellulose uu si buuxda u kala firdho oo uu u milmo. Guud ahaan, boorashka waxaa lagu sameeyaa iyadoo lagu qaso lix qaybood oo dareere dabiici ah ama biyo baraf ah hal qayb oo ka mid ah hydroxyethyl cellulose. Ka dib qiyaastii 5-30 daqiiqo, hydroxyethyl cellulose waa la dhalaalin doonaa oo si cad ayuu u barari doonaa. (Xusuusnow in qoyaanka biyaha guud uu aad u sarreeyo xagaaga, sidaa darteed waa inaan loo isticmaalin in lagu qalabeeyo boorashka.)
2. Si toos ah ugu dar hydroxyethyl cellulose marka aad shiidiayso midabka: Habkani waa mid fudud oo qaadanaya waqti gaaban. Habka faahfaahsan waa sidan soo socota:
(1) Ku dar xaddi ku habboon oo biyo la safeeyey ah baaldi weyn oo ah isku-darka sare (guud ahaan, qalabka sameynta filimada iyo walxaha qoynta ayaa lagu daraa waqtigan)
(2) Bilow inaad si joogto ah u walaaqdo xawaare hoose oo si tartiib ah oo siman ugu dar hydroxyethyl cellulose
(3) Sii wad walaaq ilaa dhammaan walxaha si siman loo kala firdhiyo oo la qooyo
(4) Ku dar waxyaabaha lagu daro caariyaysiga si loo hagaajiyo qiimaha PH
(5) Walaaq ilaa dhammaan hydroxyethyl cellulose ay gebi ahaanba milmaan (dhegxaanta xalka ayaa si weyn u kordheysa), ka dibna ku dar qaybo kale qaacidada, oo shiidi ilaa rinjigu samaysmo.
3. Diyaari hydroxyethyl cellulose oo leh khamriga hooyada si aad u isticmaasho mustaqbalka: Habkani waa in marka hore la diyaariyo khamriga hooyada oo leh xoog badan, ka dibna lagu daro rinjiga latex. Faa'iidada habkani waa inuu yahay mid dabacsan oo si toos ah loogu dari karo rinjiga la dhammeeyay, laakiin waa in si habboon loo kaydiyaa. Tallaabooyinka iyo habku waxay la mid yihiin tallaabooyinka (1)-(4) ee habka 2, farqiga ayaa ah in aan loo baahnayn kicinta xiirashada sare, oo kaliya qaar ka mid ah kiciyeyaasha awoodda ku filan si ay u ilaaliyaan faybarka hydroxyethyl si siman ugu kala firdhisan xalka ayaa ah Can. Sii wad inaad si joogto ah u walaaqdo ilaa ay si buuxda ugu milmaan xal fiiqan. Waa in la ogaadaa in wakiilka antifungal-ka lagu daro khamriga hooyada rinjiga sida ugu dhakhsaha badan.
4 Arrimood oo u baahan fiiro gaar ah marka la diyaarinayo khamriga hydroxyethyl cellulose
Maadaama hydroxyethyl cellulose uu yahay budo la warshadeeyay, way fududahay in la maareeyo oo lagu milmo biyo ilaa inta la tixgelinayo qodobbada soo socda.
(1) Kahor iyo ka dib marka lagu daro hydroxyethyl cellulose, waa in si joogto ah loo walaaqaa ilaa xalka uu noqdo mid gebi ahaanba hufan oo cad.
(2) Waa in si tartiib tartiib ah loogu shaandheeyaa haanta isku darka, oo si toos ah haanta isku darka haanta uguma darin xaddi badan oo hydroxyethyl cellulose ah oo sameeyay buro ama kubbado.
(3) Heerkulka biyaha iyo qiimaha pH ee biyaha ku jira waxay xiriir muhiim ah la leeyihiin kala dirista hydroxyethyl cellulose, sidaa darteed waa in fiiro gaar ah la siiyaa.
(4) Ha ku darin walxo alkaline ah isku darka ka hor inta aan budada hydroxyethyl cellulose lagu qooyin biyo. Kordhinta pH ka dib marka la qoyo waxay gacan ka geysataa kala dirida.
(5) Inta ugu macquulsan, ku dar wakiilka ka hortagga fungal goor hore.
(6) Marka la isticmaalayo hydroxyethyl cellulose oo leh viscosity sare, heerka khamriga hooyada waa inaanu ka badnayn 2.5-3% (miisaan ahaan), haddii kale khamriga hooyada way adkaan doontaa in la maareeyo.
Arrimaha saameeya daxalka rinjiga latex:
(1) Sababtoo ah walaaq xad dhaaf ah, qoyaanka ayaa aad u kululaada inta lagu jiro kala firdhinta.
(2) Tirada dhumuc-dhejiyeyaasha kale ee dabiiciga ah ee ku jira qaab-dhismeedka rinjiga iyo saamiga tirada ee hydroxyethyl cellulose.
(3) In xaddiga surfactant-ka iyo xaddiga biyaha loo isticmaalay qaacidada rinjiga ay ku habboon yihiin.
(4) Marka la samaynayo latex, xaddiga oksaydhka sida kataliyaha haraaga ah.
(5) Daxalka dhumuc-dhegaha oo ay sameeyaan noolaha yaryar.
(6) Habka rinjiyeynta, in taxanaha tallaabada ee lagu darayo dhumuc-dhejinta ay ku habboon tahay iyo in kale.
