IPolyvinylpyrrolidone
Polyvinylpyrollidone (PVP) Iimveliso zeBanga lobuGcisa zikhona njengomgubo nefom yesisombululo samanzi, kwaye zinikezelwa kuluhlu olubanzi lobunzima beemolekyuli, zinyibilika ngokulula emanzini, etywaleni nakwezinye izinyibilikisi zendalo. uzinzo lwekhemikhali, akukho netyhefu.

Izicelo:
I-PVP yebakala lobuchwephesha isetyenziswa Impahla elukilweyo / ifayibha, izinto zokuncamathelisa, ukugquma / ukupeyinta, ukuhlamba impahla / isepha yekhaya, ii-Inks, iiCeramics kunye namanye amashishini e-hi-tech.
* Ukudluliselwa kwedayi kuthintelo kwizicoci ezisebenzisa i-PVP K15, K17 & K30 kunye / okanye imveliso yayo engamanzi kwimbaleki enzima.
* Ukuhlanjululwa kwedayi eyolukiweyo kunye nolawulo lwereyithi yesitrayikhi ngokudityaniswa nokusasazwa ngePVP K30 kunye / okanye imveliso yayo engamanzi.
* Izinto zokuhlamba iimpahla apho i-PVP K30 inqanda ukubekwa kwakhona komhlaba.
* I-Emulsion polymerization apho i-PVP K30 kunye okanye imveliso yayo ye-latex stabilizer, esebenza njenge-colloid yokukhusela, iququzelela ukuhanjiswa kwakhona kwesicelo 'sokuqhekeka' sokugqibela.
Ukusasazeka kusetyenziswa i-PVPK30 kunye ne-K90 kunye / okanye imveliso yayo engamanzi yedayi engabonakaliyo kunye neenkqubo zokubhalwa kweinki ezisekwe kumbala.
* Ukwenziwa kwembumba yenwebu engenanto apho i-PVP K90 kunye ne-K30 kunye / okanye imveliso yayo engamanzi idala ukusilela kwayo nayiphi na imimandla ye-hydrophilic in membranes ze-polysulfone.
* Kwi-oyile efayilwayo, ''
* Kwipleyiti ze lithographic zisebenzisa i-hydrophobic inks, apho i-PVPK15 ibonelela ukuphucula indawo engafakwanga.
* I-PVP K80, i-K85 kunye ne-K90 kunye / okanye iimveliso zayo ezingamanzi kwizinti zokuncamathela ezisekwe kubugcisa nakwizicelo zobugcisa.
* Kwifayibha yokulinganisa ubungakanani beglasi, kusetyenziswa i-PVP K30 kunye ne-K90 kunye / okanye imveliso yayo yefilimu eyenza isenzo ukukhuthaza ukunamathela kwe-polyivnylacetate.
* Njengezibophelelo ezinokutsha zeceramic, kusetyenziswa i-PVP K30 & K90 kunye / okanye imveliso yayo engamanzi ukomeleza amandla aluhlaza.
