Kor iyo hoos ee Hydroxyethyl Cellulose

Marka la eego wax soo saarka iyo ka faa'iidaysiga Hydroxyethyl Cellulose (HEC), ereyada "kor u kaca" iyo "hoosta" waxay tilmaamayaan marxalado kala duwan ee silsiladda sahayda iyo silsiladda qiimaha, siday u kala horreeyaan. Waa kan sida shuruudahan loogu dabaqo HEC:

Xagga sare:

1. Soo saarista alaabta ceeriin: Tani waxay ku lug leedahay soo iibinta alaabta ceeriin ee looga baahan yahay soo saarista HEC. Cellulose, alaabta ceeriin aasaasiga ah ee wax soo saarka HEC, sida caadiga ah waxaa laga helaa ilo dabiici ah oo kala duwan sida saxarka alwaax, suufka suufka, ama qalabka kale ee dhirta fiber.
2. Firfircoonida Cellulose: Kahor eterification ka hor, walxaha ceeriin ee cellulose waxaa laga yaabaa inay maraan habka firfircoonida si ay u kordhiso falcelinta iyo helitaankeeda wax ka beddelka kiimikaad ee xiga.
3. Habka Etherification: Habka etherification wuxuu ku lug leeyahay falcelinta cellulose leh ethylene oxide (EO) ama ethylene chlorohydrin (ECH) iyada oo ay jiraan kiciyayaal alkaline ah. Talaabadani waxay soo bandhigaysaa kooxaha hydroxyethyl ee laf dhabarta cellulose, taasoo keenaysa HEC.
4. Nadiifinta iyo Soo kabashada: Ka dib falcelinta etherification, sheyga HEC ee cayriin waxa uu maraa tillaabooyin sifeyn si looga saaro wasakhda, reagen-yaasha aan falcelinta lahayn, iyo alaabta ka soo baxda. Hababka soo kabashada waxa kale oo la isticmaali karaa si loo soo ceshado dareerayaasha iyo dib u warshadaynta alaabta qashinka.

Hooska hoose:

1. Samaynta iyo Isku-dhafka: Hoos-u-dhaca wax-soo-saarka, HEC waxaa lagu daray qaabab kala duwan iyo xeryahooda codsiyada gaarka ah. Tani waxay ku lug yeelan kartaa isku darka HEC iyo polymers kale, wax lagu daro, iyo maaddooyinka si loo gaaro sifooyinka la doonayo iyo sifooyinka waxqabadka.
2. Wax-soo-saarka Alaabta: Badeecadaha la habeeyey ee ay ku jiraan HEC waxaa lagu soo saaray habraacyo ay ka mid yihiin isku-dhafka, saarista, qaabeynta, ama shubista, iyadoo ku xiran codsiga. Tusaalooyinka wax soo saarka hoose waxaa ka mid ah rinjiga, dahaarka, xabagta, alaabta daryeelka shakhsi ahaaneed, daawooyinka, iyo qalabka dhismaha.
3. Baakadaha iyo Qaybinta: Alaabooyinka la dhammeeyay waxaa lagu baakadeeyay weelal ama baakado badan oo ku habboon kaydinta, gaadiidka, iyo qaybinta. Tani waxay ku lug yeelan kartaa calaamadaynta, summaynta, iyo u hoggaansanaanta shuruudaha sharci ee badbaadada iyo macluumaadka alaabta.
4. Codsiga iyo Isticmaalka: Isticmaalayaasha dhamaadka ah iyo macaamiishu waxay u isticmaalaan alaabooyin ay ku jiraan HEC ujeedooyin kala duwan, iyadoo ku xidhan codsiga gaarka ah. Tan waxa ku jiri kara rinjiyeynta, dahaarka, isku xidhka xabagta, daryeelka shakhsi ahaaneed, samaynta dawooyinka, dhismaha, iyo codsiyada kale ee warshadaha.
5. Tuuritaanka iyo Dib-u-warshadaynta: Ka dib isticmaalka, alaabta ay ku jiraan HEC waxaa laga yaabaa in lagu tuuro iyada oo loo marayo hababka maaraynta qashinka ee habboon, taas oo ku xidhan xeerarka deegaanka iyo tixgelinta deegaanka. Ikhtiyaarada dib u warshadaynta ayaa laga yaabaa inay diyaar u yihiin agabyada qaarkood si ay dib ugu soo ceshadaan ilaha qiimaha leh.

Marka la soo koobo, marxaladaha kor u kaca ee wax soo saarka HEC waxay ku lug leeyihiin soo saarista alaabta ceeriin, kicinta cellulose, etherification, iyo nadiifinta, halka hawlaha hoose ay ka mid yihiin samaynta, wax soo saarka, baakadaha, qaybinta, codsiga, iyo qashinka / dib u warshadaynta alaabta ay ku jiraan HEC. Labada hab ee kor iyo hoosba waa qaybo muhiim ah oo ka mid ah silsiladda sahayda iyo silsiladda qiimaha ee HEC.
