PPH bụ mmiri mmiri doro anya na-enweghị agba, nwere isi ụtọ na-esi ísì ụtọ. Ọ naghị egbu egbu ma dịkwa mma maka gburugburu ebe obibi iji belata mmetụta V°C agba dị egwu. Ebe ọ bụ na emulsion mmiri dị iche iche na mkpuchi mgbasa na agba na-egbuke egbuke na-arụ ọrụ nke ọma. Ọ bụ vinyl acetate, acrylic esters, styrene - ihe mgbaze siri ike nke ụdị acrylate dị iche iche, obere mmiri na-agbaze (erughị ọnụego mmiri na-ekupụ, na-enyere aka ịza aza), iji hụ na ihe ndị dị na latex na-amịkọrọ ya kpamkpam, mepụtara ihe mkpuchi dị mma na-aga n'ihu iji nye latex coalescence arụmọrụ kacha mma na mmepe agba, mana ọ nwekwara ezigbo nkwụsi ike nchekwa. Ma e jiri ya tụnyere ihe mgbakwunye na-emepụta ihe nkiri nkịtị dị ka TEXANOL (ester mmanya ester nke e ji aka mee bụ -12), nke e guzobere nke ọma na fim ahụ, otu ihe na-egbuke egbuke, mmiri mmiri, mgbochi ịcha, mmepe agba, n'okpuru scrub na ọnọdụ ndị ọzọ, PPH na-ebelata ihe dị ka 30-50%. Ike coalescence siri ike, arụmọrụ itinye ihe n'ime ya ugboro 1.5-2, ọnụ ahịa mmepụta adalatala nke ukwuu. Maka ọtụtụ emulsions, PPH tinyere na emulsion ahụ nke 3.5-5%, okpomọkụ kacha nta nke imepụta ihe nkiri (MFT) nke ruru -1°C.
Dosaji:
1. PPH na-akwado ka ị tinye tupu emulsion, ma ọ bụ tinye na pigment egweri ogbo, yabụ PPH formulations na ihe ndị ọzọ dị mfe ijikọ, ọkacha mma emulsified na gbasaa, yabụ agaghị emetụta nkwụsi ike nke pigment na mmekọahụ yiri ya.
2. N'ozuzu, a na-etinye ego mgbakwunye nke 3.5 ruo 6% acrylic emulsion, acrylic emulsion maka mmanya vaịn na ego nke 2.5-4.5% maka styrene-acrylic n'ozuzu 2-4%.
