HEC heerka rinjiga

heerka rinjigaHEC Hydroxyethyl cellulose waa nooc ka mid ah polymer-ka aan biyaha ku milmin ee aan ionic ahayn, budo cad ama jaalle ah, si fudud loo socodsiin karo, ur iyo dhadhan la'aan ah, wuxuu ku milmi karaa biyaha qabow iyo kuwa kulul labadaba, heerka kala diridduna wuu kordhaa marka heerkulka la gaaro, guud ahaan kuma milmi karo inta badan dareerayaasha dabiiciga ah. Waxay leedahay xasillooni PH oo wanaagsan iyo isbeddel yar oo ku yimaada heerka ph2-12. HEC waxay leedahay iska caabin milix sare iyo awood hygroscopic, waxayna leedahay haynta biyaha hydrophilic oo xooggan. Xalkeeda biyaha leh wuxuu leeyahay firfircooni dusha sare ah, alaabada viscosity sare lehna waxay leeyihiin pseudoplasticity sare. Waxaa laga dhigi karaa filim hufan oo aan biyo lahayn oo leh xoog dhexdhexaad ah, oo aan si fudud u wasakhayn saliid, aan saameyn iftiinku ku yeelan, wali wuxuu leeyahay filim biyo ku milma HEC. Ka dib daaweynta dusha sare, HEC way kala firdhisaa mana midowdo biyaha, laakiin si tartiib ah ayay u milmaysaa. PH waxaa loo hagaajin karaa 8-10 si dhakhso ahna wuu u milmaa.

Sifooyinka ugu muhiimsan

Hcellulose ydroxyethyl(HEC)waa in lagu milmi karo biyo qabow iyo biyo kulul, mana laha astaamo jel ah. Waxay leedahay noocyo badan oo beddel ah, milmi kara iyo daxal. Waxay leedahay xasillooni kuleyl oo wanaagsan (ka hooseeya 140°C) mana soo saarto xaalado aashito ah. Roob. Xalka hydroxyethyl cellulose (HEC) wuxuu samayn karaa filim hufan, kaas oo leh astaamo aan ionic ahayn oo aan la falgalin ions oo leh iswaafajin wanaagsan.

Sida colloid ilaalin ah, HEC-ga heerka rinjiga ayaa loo isticmaali karaa polymerization-ka emulsion-ka vinyl acetate si loo hagaajiyo xasilloonida nidaamka polymerization-ka ee baaxadda PH-ga ballaaran. Soo saarista alaabada la dhammeeyay si loo sameeyo midabaynta, buuxinta iyo waxyaabaha kale ee lagu daro si siman u kala firdhisan, deggan oo bixiya saameyn dhumuc leh. Waxa kale oo loo isticmaali karaa styrene, acrylic, acrylic iyo polymers kale oo la hakiyey sida kala firdhiyeyaal, oo loo isticmaalo rinjiga latex si weyn ayuu u hagaajin karaa dhumucda, wuxuuna hagaajin karaa waxqabadka siman.

Qeexitaanka Kiimikada

Badeecadaha Darajooyinka 

Habka loo adeegsado hydroxyethyl cellulose HEC ee biyaha ku jirarinji

1. Ku dar si toos ah marka aad shiidiayso midabka: habkani waa kan ugu fudud, waqtiga la isticmaalayna waa gaaban yahay. Tallaabooyinka faahfaahsan waa sidan soo socota:

(1) Ku dar biyo nadiif ah oo ku habboon VAT-ga kicinta jarista sare (guud ahaan, ethylene glycol, wakiilka qoynta iyo wakiilka sameynta filimada ayaa lagu daraa waqtigan)

(2) Bilow inaad ku walaaqdo xawaare hoose oo si tartiib ah ugu dar hydroxyethyl cellulose

(3) Sii wad walaaq ilaa dhammaan walxaha la qooyo

(4) ku dar daawada caariyaysiga, habeeyaha PH, iwm.

(5) Walaaq ilaa dhammaan hydroxyethyl cellulose ay gebi ahaanba milmaan (dhegxaanta xalka ayaa si weyn u kordheysa) ka hor inta aan lagu darin qaybaha kale ee qaacidada, oo shiidi ilaa ay noqoto rinji.

2. Waxaa lagu qalabeeyay dareere hooyada sugaysa: habkan marka hore waxaa lagu qalabeeyay dareere hooyada oo sareeya, ka dibna waxaa lagu daraa rinjiga latex, faa'iidada habkani waa dabacsanaan weyn, waxaa si toos ah loogu dari karaa alaabada rinjiga la dhammeeyay, laakiin waa inay noqotaa meel ku habboon. Tallaabooyinka iyo habku waxay la mid yihiin tallaabooyinka (1) - (4) ee Habka 1, marka laga reebo in aan loo baahnayn kicin sare oo goyn ah oo kaliya kicin leh awood ku filan oo ku haysa fiilooyinka hydroxyethyl si siman ugu kala firdhisan xalka ayaa ku filan. Sii wad walaaqidda ilaa ay si buuxda u milmaan una noqoto xal qaro weyn. Ogsoonow in daawada caariyaysiga lagu daro khamriga hooyada sida ugu dhakhsaha badan.

3. Sida Boorashka oo kale: Maadaama dareerayaasha dabiiciga ah ay yihiin dareerayaal xun oo loogu talagalay hydroxyethyl cellulose, dareerayaashan dabiiciga ah waxaa lagu qalabeyn karaa boorash. dareerayaasha dabiiciga ah ee ugu badan ee la isticmaalo sida ethylene glycol, propylene glycol, iyo wakiilada sameynta filimada (sida hexadecanol ama diethylene glycol butyl acetate), biyaha barafka sidoo kale waa dareere liita, sidaa darteed biyaha barafka waxaa badanaa loo isticmaalaa dareerayaasha dabiiciga ah ee boorashka ku jira. Gruel - sida hydroxyethyl cellulose si toos ah ayaa loogu dari karaa rinjiga. Hydroxyethyl cellulose waxaa lagu buuxiyay qaab boorash ah. Ka dib marka lagu daro lacquer, isla markiiba mil oo yeelo saameyn dhumuc leh. Ka dib marka lagu daro, sii wad walaaq ilaa hydroxyethyl cellulose ay si buuxda u milmaan oo ay isku mid noqoto. Boorash caadi ah waxaa lagu sameeyaa iyadoo la isku darayo lix qaybood oo dareere dabiici ah ama biyo baraf ah oo leh hal qayb oo ka mid ah hydroxyethyl cellulose. Ka dib qiyaastii 5-30 daqiiqo, darajada rinjigaHECXagaaga, qoyaanka biyuhu aad ayuu u sarreeyaa oo loo isticmaali karaa boorashka.

4. Arrimaha u baahan fiiro gaar ah marka la qalabeynayo khamriga hooyada ee hydroxyethyl cellulose:

Ptaxaddarro

1 Kahor iyo ka dib ku darista darajada rinjigaHEC, waa in si joogto ah loo walaaqaa ilaa xalka uu noqdo mid gebi ahaanba hufan oo cad.

2. Si tartiib ah ugu shaandhee hydroxyethyl cellulose haanta isku darka. Ha ku darin haanta isku darka tiro badan ama si toos ah ugu darin heerka rinjiga ee tirada badan ama wareegsan.HEC.

3 heerkulka biyaha iyo qiimaha pH ee biyuhu waxay xiriir cad la leeyihiin kala dirista heerka rinjigaHECcellulose hydroxyethyl, sidaa darteed waa in fiiro gaar ah loo yeesho.

Ha ku darin walxo aasaasi ah isku darka ka hor inta aan la saarin rinjigaHECBudada hydroxyethyl cellulose waxaa lagu qooyaa biyo. Kordhinta pH-ga ka dib marka la qooyo waxay ka caawisaa milmida.

5. Inta suurtogalka ah, ku darista hore ee daawada ka hortagga caariyaysiga.

6 Marka la isticmaalayo viscosity sare heerka rinjigaHEC, heerka khamriga hooyada waa inaanu ka badnayn 2.5-3% (miisaan ahaan), haddii kale khamriga hooyada way adag tahay in la shaqeeyo.

Arrimaha saameeya daxalka rinjiga latex

1. Inta xumbo hawo ah ee ku harsan rinjiga ay sii badanayaan, ayaa dheellitirka sare u kacayaa.

2. Ma isku mid baa cadadka firfircoonida iyo biyaha ku jira qaacidada rinjiga?

3 ee ku jira isku-darka latex, hadhaaga oksaydhka kiciyaha ee xaddiga.

4. Qiyaasta dhumuc-dhejiyeyaasha kale ee dabiiciga ah ee ku jira qaacidada rinjiga iyo saamiga qiyaasta ee heerka rinjigaHEC.)

5. habka loo samaynayo rinjiga, habka loo raacayo tallaabooyinka lagu darayo dhumuc-dhererka ayaa ku habboon.

6. Sababo la xiriira kacsanaan xad dhaaf ah iyo qoyaan xad dhaaf ah inta lagu jiro kala firdhinta.

7. Nabaad-guurka microbial ee dhumuc-dheeraha.
