Tsarin Samarwa na Redispersible Polymer Foda

Tsarin samar da foda mai sake narkewa (RPP) ya ƙunshi matakai da dama, ciki har da polymerization, busar da feshi, da kuma bayan sarrafawa. Ga taƙaitaccen bayani game da tsarin samarwa na yau da kullun:

1. Yin amfani da polymerization:

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

1. Shiri na Monomer: Ana tsarkake Monomers kuma a gauraya su da ruwa, masu farawa, da sauran abubuwan ƙari a cikin jirgin ruwa na reactor.
2. Haɗakar da monomer: Cakuda monomer yana shiga cikin haɗaɗɗiyar polymerization a ƙarƙashin yanayin zafi, matsin lamba, da yanayin tashin hankali. Masu farawa suna fara amsawar polymerization, wanda ke haifar da samuwar sarƙoƙin polymer.
3. Daidaitawa: Ana ƙara surfactants ko emulsifiers don daidaita watsawar polymer da hana haɗuwa ko haɗuwa da ƙwayoyin polymer.

2. Busar da feshi:

Bayan an yi polymerization, ana busar da polymer ɗin ta hanyar feshi don mayar da shi foda mai busasshe. Busar da polymer ɗin ta ƙunshi atomization na watsawa zuwa ƙananan ɗigo, sannan a busar da shi a cikin ruwan zafi.

1. Atomization: Ana tura watsawar polymer zuwa bututun feshi, inda ake ƙara shi zuwa ƙananan ɗigon ruwa ta amfani da iska mai matsewa ko na'urar centrifugal.
2. Busarwa: Ana shigar da digo-digo a cikin ɗakin busarwa, inda suke haɗuwa da iska mai zafi (yawanci ana dumama su zuwa yanayin zafi tsakanin 150°C zuwa 250°C). Ƙafewar ruwa cikin sauri daga digo-digo yana haifar da samuwar ƙwayoyin cuta masu tauri.
3. Tarin Barbashi: Ana tattara busassun barbashi daga ɗakin busarwa ta amfani da iska mai ƙarfi ko matattarar jaka. Ƙananan barbashi na iya shiga ƙarin rarrabuwa don cire manyan barbashi da kuma tabbatar da rarraba girman barbashi iri ɗaya.

3. Bayan Aiwatarwa:

Bayan busar da feshi, RPP yana ɗaukar matakai bayan an sarrafa shi don inganta halayensa da kuma tabbatar da daidaiton samfurin.

1. Sanyaya: Ana sanyaya busasshen RPP zuwa zafin ɗaki don hana sha danshi da kuma tabbatar da daidaiton samfurin.
2. Marufi: Ana sanyaya RPP ɗin a cikin jakunkuna ko kwantena masu jure da danshi don kare shi daga danshi da danshi.
3. Kula da Inganci: Ana gwada RPP don tabbatar da ingancinsa da halayensa na zahiri da na sinadarai, gami da girman barbashi, yawan yawa, danshi da ya rage, da kuma abubuwan da ke cikin polymer.
4. Ajiya: Ana adana RPP ɗin da aka shirya a cikin muhalli mai tsari don kiyaye kwanciyar hankali da tsawon lokacin shiryawa har sai an aika shi ga abokan ciniki.

Kammalawa:

Tsarin samar da foda mai sake narkewa ya haɗa da haɗakar monomers don samar da watsawar polymer, sannan a busar da feshi don mayar da watsawar zuwa busasshiyar foda. Matakan bayan sarrafawa suna tabbatar da ingancin samfura, kwanciyar hankali, da marufi don ajiya da rarrabawa. Wannan tsari yana ba da damar ƙera RPPs masu aiki iri-iri da yawa waɗanda ake amfani da su a masana'antu daban-daban, gami da gini, fenti da shafi, manne, da yadi.
