Tsarin Samar da Foda na Polymer Redispersible

Tsarin samar da foda na polymer foda (RPP) ya ƙunshi matakai da yawa, ciki har da polymerization, bushewar feshi, da kuma bayan aiwatarwa. Anan ga bayyani na tsarin samarwa na yau da kullun:

1. Polymerization:

Tsarin yana farawa tare da polymerization na monomers don samar da barga na polymer watsawa ko emulsion. Zaɓin monomers ya dogara da kaddarorin da ake so da aikace-aikacen RPP. Abubuwan monomers na yau da kullun sun haɗa da vinyl acetate, ethylene, butyl acrylate, da methyl methacrylate.

1. Shirye-shiryen Monomer: Ana tsarkake monomers kuma ana haɗe su da ruwa, masu haɓakawa, da sauran abubuwan ƙari a cikin jirgin ruwa.
2. Polymerization: Cakudar monomer yana jurewa polymerization ƙarƙashin yanayin zafi mai sarrafawa, matsa lamba, da yanayin tashin hankali. Masu ƙaddamarwa suna ƙaddamar da halayen polymerization, wanda ke haifar da samuwar sarƙoƙi na polymer.
3. Tsayawa: Ana ƙara abubuwan da ake amfani da su ko emulsifiers don daidaita tarwatsawar polymer da hana coagulation ko haɓaka ƙwayoyin polymer.

2. Fesa bushewa:

Bayan polymerization, da polymer watsawa ne hõre fesa bushewa don maida shi a cikin busasshen foda form. Busasshen fesa ya ƙunshi atomizing da tarwatsewar zuwa cikin ɗigon ruwa masu kyau, waɗanda sai a bushe su a cikin rafin iska mai zafi.

1. Atomization: Ana fitar da tarwatsewar polymer zuwa bututun feshi, inda aka karkatar da shi cikin kananan ɗigon ruwa ta amfani da matsewar iska ko atomizer na centrifugal.
2. Bushewa: Ana shigar da ɗigon ruwa a cikin ɗakin bushewa, inda suke haɗuwa da iska mai zafi (yawanci zafi tsakanin 150 ° C zuwa 250 ° C). Saurin fitar da ruwa daga ɗigon ruwa yana haifar da samuwar ƙwai mai ƙarfi.
3. Tarin Barbashi: Ana tattara busassun barbashi daga ɗakin bushewa ta amfani da guguwa ko matattarar jaka. Kyawawan barbashi na iya fuskantar ƙarin rarrabuwa don cire ɓangarorin da ba su da girma da kuma tabbatar da rarraba girman barbashi iri ɗaya.

3. Bayan Gudanarwa:

Bayan bushewar feshi, RPP tana ɗaukar matakan sarrafawa don haɓaka kaddarorinta da tabbatar da kwanciyar hankali na samfur.

1. Cooling: An sanyaya busasshen RPP zuwa zafin jiki don hana ɗaukar danshi da tabbatar da daidaiton samfur.
2. Marufi: RPP ɗin da aka sanyaya an haɗa shi cikin jakunkuna ko kwantena masu jurewa danshi don kare shi daga danshi da zafi.
3. Ingancin Inganci: RPP tana fuskantar gwajin sarrafa inganci don tabbatar da kaddarorin sa na zahiri da sinadarai, gami da girman barbashi, yawan yawa, ragowar danshi, da abun ciki na polymer.
4. Adana: An adana RPP ɗin da aka haɗa a cikin yanayin sarrafawa don kiyaye kwanciyar hankali da rayuwar rayuwar sa har sai an tura shi ga abokan ciniki.

Ƙarshe:

Samar da tsari na redispersible polymer foda ya ƙunshi polymerization na monomers don samar da wani polymer watsawa, bi da feshi bushewa don maida watsawa a cikin wani busasshen foda form. Matakan aiki na baya sun tabbatar da ingancin samfurin, kwanciyar hankali, da marufi don ajiya da rarrabawa. Wannan tsari yana ba da damar ƙera RPP masu aiki iri-iri da ake amfani da su a masana'antu daban-daban, gami da gine-gine, fenti da sutura, adhesives, da yadi.
