Mtayarishaji: SINOPEC

PVA ina mali nyingi ya kipekee kama vile umumunyifu maji, fiber-kutengeneza mali, adhesiveness, na kutengeneza filamu mali, Emulsion utulivu, utulivu utawanyiko, upinzani dhidi ya mafuta, asidi, na alkali, kemikali reactivity, biodegradability, pamoja na meltability (au thermoplasticity) na wengi kipekee na ya pekee mali kwa njia ya modification.PVA sana kutumika katika viwanda vingi kama nguo, papermaking, ujenzi, kemikali, uchapishaji, ufungaji, dawa, sabuni & vipodozi, kilimo, keramik, chuma na chuma, vifaa vya umeme, electrolysis, electroplating, na na kadhalika.

maombi:                                                                                                                          

PVA, ambayo ni bora katika ulinzi colloid na ina shughuli bora uso, mara nyingi hutumika kama utawanyiko kiimarishaji kwa kusimamishwa upolimishaji ya monoma vinyl hidrojeni (VCM). utendaji wa PVC resin inaweza sana optimized kwa kuchagua kufaa PVA daraja na shahada sahihi ya upolimishaji na hidrolisisi.

Emulsion Stabilizer & Binder

PVA inaweza kutumika sana kama colloid kinga au thickener kwa Emulsion upolimishaji ya vinyl acetate (VAC) au VAC / acrylate. ina sifa zifuatazo: bora adhesiveness, kuongezeka awali nia na kiwango cha kukausha wakati kutumika kwa filler; upinzani bora oiloutstanding nguvu filamu, kudumu na utendaji imara.

fiber upotoshaji

maombi mawili muhimu ya PVA ni kutumika kama Vinylon feedstock na sizing wakala textile.As malighafi ya Vinylon fiber, ina faida ya kuwa ya juu katika nguvu, ngozi unyevu, abrasion upinzani, jua, upinzani kutu na rangi nyeupe. Pia inaweza spun kwa pamba, pamba na viscose fiber au rena spun kwa itself.As sizing wakala nguo, Itakuwa corrode au kuzorota kwa kujitoa nzuri ya pamba, katani, polyester na viscose nyuzi.

PVA inaweza kutumika kuzalisha maji mumunyifu filamu na maji-upinzani filamu. PVA inapatikana katika bidhaa sumu ambayo kuonyesha sifa ya asili ya PVA, yaani, nguvu high tensile, upinzani dhidi ya kutengenezea kikaboni na tightness.They hewa ni wote sana kutumika katika sekta ya mfuko, si tu kwa ajili ya nguo, lakini pia kwa kemikali, chakula, kemikali za kila siku, kemikali za kilimo, dyestuff, na kadhalika

Pulp & Paper
