HoʻohanaʻO ka PPH he wai aniani ʻole kala me kahi ʻala ʻono ʻono. He mea kupaianaha kona ʻano ʻawaʻawa a pili i ke kaiapuni e hōʻemi i ka pena V°C. He mea kūpono loa ka coalescent i nā ʻano emulsion wai like ʻole a me nā uhi hoʻopuehu i ka pena gloss a me ka semi-gloss. He vinyl acetate, acrylic esters, styrene - he mea hoʻoheheʻe ikaika o nā ʻano polymer acrylate like ʻole, he wai liʻiliʻi e hoʻoheheʻe ʻia (ʻoi aku ka liʻiliʻi ma mua o ka nui o ka mahu wai, kōkua i nā ʻāpana pehu), e hōʻoia i ka hoʻopili piha ʻia e nā ʻāpana latex, i hoʻokumu ʻia i kahi kiʻiʻoniʻoni uhi hoʻomau maikaʻi loa e hāʻawi i ka latex coalescence hana maikaʻi loa a me ka hoʻomohala kala, akā he kūpaʻa maikaʻi hoʻi ka mālama ʻana. Hoʻohālikelike ʻia me nā mea hoʻohui hana kiʻiʻoniʻoni maʻamau e like me TEXANOL (ʻo ka ester waiʻona homemade he -12), i hoʻokumu piha ʻia i loko o ke kiʻiʻoniʻoni, ka gloss like, ka fluidity, anti-sagging, ka hoʻomohala kala, ma lalo o ka scrub a me nā kūlana ʻē aʻe, hoʻemi ka PPH i ka nui o kahi 30-50%. Ka hiki ke coalescence ikaika, ka pono o ka waiho ʻana i hoʻohui ʻia he 1.5-2 mau manawa, ua hāʻule nui nā kumukūʻai hana. No ka hapa nui o nā emulsions, ua hoʻohui ʻo PPH i ka emulsion i kahi nui o 3.5-5%, ʻo ka mahana hana kiʻiʻoniʻoni liʻiliʻi loa (MFT) a hiki i -1°C.
Ka nui o ka lāʻau:
1. Manaʻo ʻia e hoʻohui ʻo PPH ma mua o ka emulsion, a i ʻole e hoʻohui i ke kahua wili pigment, no laila e maʻalahi ka hoʻopili ʻana o nā ʻano PPH a me nā mea hoʻohui ʻē aʻe, ʻoi aku ka maikaʻi o ka emulsified a me ka hoʻopuehu ʻia, a no laila ʻaʻole ia e hoʻopilikia i ke kūpaʻa o ka pigment a me nā mea like.
2. Ma keʻano laulā, ʻo ka nui o ka hoʻohui ʻana o 3.5 a 6% acrylic emulsion, acrylic emulsion no ka vīnega i hoʻohui ʻia i ka nui o 2.5-4.5% no ka styrene-acrylic ma keʻano laulā 2-4%.
Pūʻolo：200 kg / pahu a i ʻole 25 kg / pahu plastik a e like me nā koi a ka mea kūʻai aku.
Ka mālama ʻana：ʻAʻole kēia huahana he huahana weliweli, pono e mālama ʻia ma kahi maloʻo a me kahi anu.
