Aqoonta Aasaasiga ah ee budada polymer

1. Fikradda aasaasiga ah
Budada polymberslem polymer waa wax lagu daro ugu weyn ee loogu talagalay budada qallalan ee budada ah ee isku dhafka ah sida salka ku-saleysan ama ku saleysan gypsum-ku-saleysan.
Budada cinjirka 'latex' ee loo yaqaan 'the the pumphed' Sababtoo ah dusha sare ee walxaha waxaa lagu daboolaa budo, budo u adkaysi u adkaysiga, waxaan helnaa budada polymer-ka qalalan. Aad bay u fududahay in lagu shubo iyo boorso loogu talagalay kaydinta bakhaarada. Marka budada lagu qaso biyo, sibidhka ama madaafiic ku saleysan gypsum, waa la tacaali karaa, iyo walxaha aasaasiga ah (2um) waxay u dhigan doonaan dowlad u dhiganta tawada asalka ah, sidaa darteed waxaa lagu magacaabaa budada lataliyaha latex.

Waxay leedahay tahriib wanaagsan, dib u kala firdhin emulsion taabashada biyaha, waxayna leedahay sifooyin isku mid ah kiimikada saxda ah sida emulsion asalka ah. Adigoo ku daraya budada polymer polymer ee ku-faafa si loo saleeyo ama budo ku saleysan budada ah ee ku-dhafka ah, madaafiicyo isku-dhafan, sifooyin kala duwan oo madaafiic ah ayaa la wanaajin karaa, sida: sida:
Hagaajinta adhition iyo wadajirka hoobiyeynta;
Yaree biyaha nuugista biyaha ee agabka iyo modulus laastikada ee maaddada;
Xoog dabacsan, iska caabbinta saamiga, iska caabinta baabi'inta iyo jiritaanka Qalabka xoojinta;
Hagaajinta waxqabadka dhismaha ee agabka, iwm.

2. Noocyada budada polymer-ka ee la kala firdhiyey
Waqtigan xaadirka ah, codsiyada ugu waaweyn ee suuqa waxaa loo qaybin karaa layaab kala firidhsan:
Vinyl acetate iyo ethelne-ka copolanymer powder (Vetylne iyo Vinyl chloride iyo doclne acid acid 'vinyl acter powermomemization (VOVENET), Vinyl Acid Acid Acid Pinyl Esters Powder Paplusymer (VOVA / verova), acrylate iyo stryreme topolaner topolaner powder (Vinyl), Vinyl Clasker estroym Powder (PVADENENEMER ENOPONYMER Powder Powder (STR), iwm.

3. Halabuurka budada polymer ee kala firidhsan
Budada polymer ee la kala firdhintu badanaa waa budo cad, laakiin in yar ayaa leh midabyo kale. Waxyaabaha ay ka kooban tahay waxaa ka mid ah:
Depiner Resinger: Waxay ku taal qaybta aasaasiga ah ee ka mid ah walxaha budada caagga ah, sidoo kale waa qaybta ugu weyn ee budada polymperser-ka ee polymissiver.
ADDIFE (gudaha): oo ay weheliso resin, waxay ciyaareysaa doorka wax ka beddelka Rein.
Waxyaabaha lagu daro (Dibedda): Qalabka dheeriga ah ayaa lagu daray si loo sii ballaariyo waxqabadka budada polymer ee la kala saari karo.
Compathoid Compant: lakab ah walxaha kudhaqan ee ku duudduubay dusha sare ee walxaha budada ah ee loo yaqaan 'the pows ​​budada' '' pappoid powers 'ee ugu badan ee loo yaqaan' latex 'ee la taabto ee' polyvinyl '.
Wakiilka ka-hortagga Cradint: Wakiilka macdanta ee wanaagsan, oo inta badan loo isticmaalo in lagu ka hortago budada caagga ah ee ku kacaya inta lagu jiro kaydinta iyo gaadiidka iyo si loo fududeeyo qulqulka budada caagga ah (ku daadinta boorsooyinka waraaqaha ama haamaha).

4. Doorka budada polymer-ka ee la kala firdhiyey
Budada cinjirka dib-u-dhigga ayaa lagu kala firdhiyaa filim iyo waxay u dhaqmaan sidii wakiil sii xoojiya sida ku dhajinaya isqabta labaad;
Colliid-ka difaaca waxaa la nuugo nidaamka madaafiicda (laguma burburin doono biyo ka dib samaynta filimka, ama "kala-firidhsiga labaad";
Resin-pinym-ka sameysan reymer-ka polymer-ka ah ayaa loo qaybiyaa inta lagu jiro nidaamka madaafiicda oo dhan iyada oo ah qalab xoojinta, iyada oo ay ku kordhinayso wadajirka madaafiicda;

5. Doorka budada polymer-ka ee la kala-fidin karo hoobiye qoyan:
Hagaajinta waxqabadka dhismaha;
Hagaajinta guryaha qulqulka;
Kordhinta Thaldotropy iyo safka safka;
hagaajinta wada-noolaanshaha;
