Habka kala dirida ee polyethylene-ka chlorine-ka ah

Qaybta xulashada dareeraha
Polyethylene-ka koloriinaysan wuxuu ku milmaa dareerayaasha sida toluene ama xylene. Milmida ester-ka waxaa lagu hagaajiyaa iyadoo la milmo esters-ka sida butyl acetate ama PMA (propylene glycol methyl ether acetate). Dareeraha polar-ka sida methanol iyo ethanol waxay sidoo kale la falgeli karaan atamka koloriin ee ku jira molecules-ka koloriinaysan ee polyethylene si ay u horumariyaan kala diridooda. Tani waa sababta oo ah molecules-ka polyethylene-ka koloriinaysan waxay leeyihiin atamka koloriin silsiladahooda, dareereyaasha polar-kana si fiican ayay ula falgeli karaan.
Arrimaha kale ee saameeya kala dirista iyo hawlaha la xiriira
Heerka koloriinaynta: Inta uu sareeyo heerka koloriinaynta ee polyethylene-ka koloriinaysan, ayaa milmidiisu badanaa kor u kacdaa, sidaa darteed polyethylene-ka koloriinaysan ee leh heerka koloriinaynta sare waxay noqon kartaa mid fudud in la milmo.
Heerkulka: Guud ahaan, marka heerkulku kordho, milmida polyethylene-ka koloriinaysan ee dareeraha ku jira ayaa sidoo kale kordheysa. Kor u qaadista heerkulka waxay gacan ka geysan kartaa dardargelinta heerka milmida, maadaama heerkulka sare uu kor u qaadi karo dhaqdhaqaaqa silsiladaha polymer-ka, taasoo dardar gelinaysa isdhexgalka dareeraha. Si kastaba ha ahaatee, badbaadada waa in la tixgeliyaa inta lagu jiro hawlgalka si looga hortago shilalka sida gubashada (tixraac saameynta heerkulku ku leeyahay kala dirista walxaha polymer-ka ee la midka ah sida alkoholka polyvinyl).
Walaaqidda (tixraac hawlgalka marka la milmayo walxaha la midka ah): Inkasta oo doorka walaaqidda inta lagu jiro walaaqidda polyethylene-ka koloriinaysan aan si cad loo sheegin, marka laga eego kala dirista walxaha polymer-ka la midka ah, walaaqidda waxay gacan ka geysataa kor u qaadista isku darka dareeraha, yaraynta kala duwanaanshaha uruurinta deegaanka, iyo dardargelinta habka kala dirista. Marka lagu darayo budada polyethylene-ka koloriinaysan dareeraha, walaaqidda waxaa la bilaabi karaa isku mar si kor loogu qaado kala dirista.
Waqtiga Kala-baxa: Si loo hubiyo kala-baxa dhammaystiran ee polyethylene-ka koloriinaysan, waxaa loo baahan yahay waqti ku filan, sida alkolada polyvinyl-ku u baahan tahay waqti ku filan oo lagu kala-baxa. Si kastaba ha ahaatee, waqtiga gaarka ah waxaa laga yaabaa in loo baahdo in lagu go'aamiyo arrimo kala duwan sida xaddiga dhabta ah ee polyethylene-ka koloriinaysan, xaddiga dareeraha, iyo heerkulka.
