Hoʻohana
ʻO ka PPH he wai aniani ʻaʻohe waihoʻoluʻu me kahi ʻala ʻala ʻoluʻolu. He mea ʻawaʻawa ʻole a pili i ke kaiapuni e hōʻemi i ka hopena pena V°C. E like me ka coalescent maikaʻi, ʻoi aku ka maikaʻi o nā emulsion wai a me nā uhi hoʻopuehu i loko o ka pena ʻālohilohi a semi-gloss. ʻO ia ka vinyl acetate, acrylic esters, styrene - ka mea hoʻoheheʻe ikaika o nā ʻano like ʻole o ka polymer acrylate, kahi wai liʻiliʻi liʻiliʻi (emi ma mua o ka nui o ka hoʻoheheʻe ʻana o ka wai, kōkua i nā ʻāpana pehu), e hōʻoia i ka hoʻopili ʻia ʻana e nā ʻāpana latex, i hana maikaʻi ʻia. ʻO ke kiʻi ʻoniʻoni hoʻopaʻa mau e hāʻawi i ka latex coalescence maikaʻi loa a me ka hoʻomohala kala, akā loaʻa nō hoʻi kahi paʻa mālama maikaʻi. Hoʻohālikelike ʻia me nā mea hoʻohui kiʻi ʻoniʻoni maʻamau e like me TEXANOL (homemade alcohol ester ʻo -12), i hoʻopiha piha ʻia i ka kiʻiʻoniʻoni, ka like o ka gloss, fluidity, anti-sagging, hoʻomohala kala, ma lalo o ka scrub a me nā kūlana ʻē aʻe, hoʻemi ka PPH i ka nui o kahi. 30-50%. ʻO ka mana coalescence ikaika, hoʻohui ʻia ka hoʻopiʻi ʻana i nā manawa 1.5-2, ua hāʻule nui nā kumukūʻai hana. No ka nui o nā emulsions, ua hoʻohui ʻia ka PPH i ka emulsion i ka nui o 3.5-5%, ka liʻiliʻi loa o ke kiʻiʻoniʻoni hana wela (MFT) a hiki i -1°C.

ʻAiʻai
1. Manaʻo ʻo PPH e hoʻohui i mua o ka emulsion, a i ʻole e hoʻohui i ke kahua wili puaʻa, no laila e maʻalahi ka hoʻopili ʻana o ka PPH a me nā mea ʻē aʻe, ʻoi aku ka maikaʻi o ka emulsified a hoʻopuehu ʻia, a no laila ʻaʻole e hoʻopilikia i ka kūpaʻa o ka puaʻa a me nā kāne like.
2.Ma keʻano laulā, hoʻohui ʻia ka nui o 3.5 a 6% acrylic emulsion, emulsion acrylic no ka vīneka i hoʻohui ʻia i ka nui o 2.5-4.5% no ka styrene-acrylic maʻamau 2-4%.

Pūʻolo
200 kg / pahu a i ʻole 25 kg / pahu pahu a e like me nā koi o ka mea kūʻai aku.

Waihona
He waiwai ʻole kēia huahana, pono e mālama ʻia ma kahi maloʻo maloʻo.
