Sida loo isticmaalo hydroxyetyl cell-ka rinjiga latex
1. Kariimka hydroxyetyl waxaa loo isticmaalaa in lagu sameeyo boorash: maadaama hyroxyetyl cellulose uusan sahlaneyn in lagula milmo solvents dabiiciga ah, qaar ka mid ah dareeraha dabiiciga ah waxaa loo isticmaali karaa diyaarinta boorash. Biyaha barafka sidoo kale waa xalal liita, sidaa darteed biyaha barafka waxaa badanaa loo isticmaalaa in lagu daro cabitaanno dabiici ah si loo diyaariyo boorash. Boorashka-sida hyroxyetyl celylule ayaa si toos ah loogu dari karaa rinjiga 'latex'. Hydroxytylylule ayaa si buuxda loo qooyay Boorashka. Markii lagu daro rinjiga, waxay si dhakhso ah u milmaysaa oo u dhaqmaan sidii dhumuc weyn. Ka dib markii lagu daro, sii wad kareyso ilaa uu kareemka biyaha ku jira ee hydroxykyl gebi ahaanba la kala firdhiyo oo kala diri. Guud ahaan, boorash waxaa lagu sameeyaa iyada oo lagu qaso lix qaybood oo ah dareeraha dabiiciga ah ama biyo baraf ah oo leh hal qayb oo ka mid ah hydroxyetyl cellule. Qiyaastii 5-30 daqiiqo ka dib, byluxytyl cely ayaa lagu dhajin doonaa biyo-bixin oo wuu bararsan yahay. (Xusuusinta in qoyaanka biyaha guud ay aad u sarreeyaan xagaaga, sidaa darteed looma adeegsan karo qalabeynta booqadka.)
2. Ku dar hydroxyetyl si toos ah marka aad shiididda midabka: Qaabkani waa mid fudud oo qaadanaya waqti gaaban. Qaabka faahfaahsan waa sida soo socota:
(1) Ku dar qadar ku habboon oo biyo nadiif ah baaldiyo weyn oo xidhashada sare ah (guud ahaan, aaladda loo sameeyo filimka iyo wakiilada qoynta ayaa lagu daray waqtigan)
(2) Bilow si isdaba joog ah si isdaba joog ah xawaare hoose oo tartiib tartiib ah oo siman oo siman ku dar hydroxytyl celluse
(3) Ku sii wado si aad u walaaq illaa inta walxaha oo dhami si siman loo kala firdhiyo loona qooyay
(4) Ku dar waxyaabaha lagu daro wax-haynta-waxtarka si aad ula qabsato qiimaha pH
(5) Walaaq ilaa inta kalusha oo dhan si galka ah loo kala diro (qaboojinta xalka ayaa si aad ah u kordhaya), ka dibna ku dar qaybo kale caanobooraha, oo shiidi ilaa rinjiga la sameeyo.
3. U diyaarso unugyada hydroxyetyl ee leh khamriga hooyaday isticmaalka dambe: Qaabkan ayaa ah in lagu diyaariyo khamriga hooyada oo leh wax ku ool ah, ka dibna ku dar rinjiga 'latex'. Faa'iidada habkan ayaa ah inay tahay mid dabacsan oo si toos ah loogu dari karo rinjiga dhameystiran, laakiin waa in si sax ah loo kaydiyaa. . Tallaabooyinka iyo habku waxay la mid yihiin tillaabooyinka (1) - (4) Habka 2, farqiga u dhexeeya ayaa ah in walxaha xarkaha sare loo baahan yahay, oo ay jiraan kuwa awood leh oo leh awood ku filan si ay u sii hayaan fiber hydroxylyl si siman loo kala firdhi karo xalka . Sii wad inaad si joogto ah u walaaqdo ilaa gabi ahaanba lagu kala diro xalka viscous. Waa in la ogaadaa in wakiilka kahortaga ka hortaga ah lagu daro khamriga hooyada velinka sida ugu dhaqsaha badan.
4 Arrimaha u baahan feejignaan markii aad diyaarineyso hyroxytyl cell-ka hooyaday khamriga
Maaddaama byroxytyl celluley uu yahay budo la warshadeeyo, way fududahay in wax laga qabto oo lagu baabi'iyo biyaha illaa iyo inta waxyaabaha soo socda loo fiirsado.
(1) ka hor iyo ka dib markii lagu daro byroxytyl bylulose, waa in si joogto ah loo kiciyaa ilaa xalka gebi ahaanba hufan oo cad.
(2) Waa in si tartiib tartiib ah loogu dhexjiraa haanta isku-darka, oo ha si toos ah ugu darin qadar aad u fara badan oo hydroxytyl cell-ka hydroxyetyl oo ka samaysan buro ama kubadaha haanta isku qasan.
(3) Heerkulka biyaha iyo qiimaha pH ee biyuhu waxay leeyihiin xiriir muhiim ah oo ay la yeeshaan huurada hydroxyetyl bylulose, sidaa darteed fiiro gaar ah waa in la bixiyaa.
(4) Ha ku darin waxyaabaha walxaha alkaline ah isku darka ka hor inta aan lagu qooyay budada unugyada unugyada biyaha ee biyaha. Kor u qaadida pH pH ka dib marka aad qoyso aaladda kala diridda AIDS-ka.
(5) Sida ugu macquulsan ee suuragalka ah, ku dar wakiilka anti-fungal goor hore.
(6) Marka la isticmaalayo ceyriska hyroxytyl-ka sareeya, ururinta khamriga ee khamriga waa inaysan ka badnayn 2.5-3% (miisaanka), haddii kale khamriga hooyadu way adkaan doontaa in la maareeyo.
Waxyaabaha saameeya sawirka rinjiga cinjirka ah:
(1) Sababo la xiriira kareyda xad-dhaafka ah, qoyaanka ayaa lagu dabiilaa inta lagu jiro kala firidhsan.
(2) Qaddarka dhumucda kale ee dabiiciga ah ee qaab-dhismeedka rinjiga iyo saamiga qaddarka si ay u hesho hydroxyetyl bylulose.
(3) Haddii tirada dusha sare iyo xaddiga biyaha loo isticmaalo qaaciddada rinjiga ay ku habboon yihiin.
(4) Marka la isku daro cinjirka 'latex', xaddiga noocyada oxide-ka ah sida haraaga haraaga ah.
(5) Xadhiga dhumucdu ku jirto microorganisms.
(6) Nidaamka sameynta rinjiga, ha ahaato tillaabada tillaabada ku darista dhumucdu waa mid ku habboon.
7 Bubles-ka badan ee hawada ayaa weli ku jira rinjiga, oo ah kan sare ee Viscocosity
