Kuyamba kwa PVC Plastic Properties ndi Common Colorants

Kutengera ndi zinthu zodabwitsa za pulasitiki ya PVC, tsopano imagwiritsidwa ntchito m'malo ambiri amoyo. Ndipo mapepala a PVC awa, nthawi zambiri amakonzedwa. Imawonjezera ma colorants ena popanga kupanga kuti zinthuzo zikhale zokongola kwambiri. Koma anthu ena sadziwa zambiri za izi, lero nkhaniyi ifotokoza mwatsatanetsatane.

PVC resin ndi thermoplastic yokhala ndi zida zosadziwika bwino. Malo ochepetsetsa a utomoni ali pafupi ndi kutentha kwa kuwonongeka. Yayamba kuwola pa 140 ℃, komanso mwachangu kwambiri pa 170 ℃. Chifukwa chokhala ndi maatomu a chloride, molekyulu ya polyethylene ndi ma copolymers ake nthawi zambiri sagwira moto ndi zinthu zozimitsa zokha komanso zopanda dontho. Ndi polima yosakhazikika kwambiri yomwe imawonongekanso ndi kuwala ndi kutentha. Ilinso ndi mphamvu yokhazikika yamankhwala, ndipo ndiyofunika kwambiri ngati anticorrosion material. PVC ndi yokhazikika kwa ma asidi ambiri a inorganic ndi maziko ndipo imagawika kwa hydrogen chloride.Itha kusungunuka mu ma ketoni ndi zosungunulira zonunkhira.

Mitundu yomwe imagwiritsidwa ntchito popanga mapulasitiki a PVC nthawi zambiri amakhala inorganic and inorganic pigments. PVC mapulasitiki ndi zofunika mkulu kwa inki, monga mkulu kutentha kukana pa processing, palibe kusamuka mu processing, kukana kuwala, etc. Ambiri ntchito colorants ndi: 1, wofiira makamaka sungunuka azo pigment, cadmium wofiira inorganic pigment, chitsulo okusayidi wofiira pigment, phthalocyanine wofiira, etc.; 2, chikasu makamaka chromium chikasu, cadmium chikasu ndi fulorosenti chikasu; 3, mtundu wa orchid makamaka phthalocyanine buluu; 4, wobiriwira makamaka phthalocyanine wobiriwira; 5, woyera makamaka amagwiritsa titaniyamu woipa; 6, wofiirira makamaka ndi pulasitiki wofiirira; 7, wakuda makamaka amakhala wakuda wa carbon. Komanso, fulorosenti whitening wothandizira ntchito whitening; golide ndi siliva ufa amagwiritsidwa ntchito posindikiza mitundu; ndi mkanda ufa astigmatism pulasitiki ngati ngale.

Ndiko kufotokozera mwatsatanetsatane "PVC pulasitiki katundu ndi mitundu wamba". Kuti mudziwe zambiri, chonde pitirizani kutchera khutu kwa ife.
