Whakamahia
He wai mārama, kore tae te PPH, he kakara reka, he kakara reka. He mea whakamiharo ngā āhuatanga kore-paitini, ā, he pai hoki mō te taiao, hei whakaiti i te pānga o te peita V°C. He tino whai hua te whakakotahitanga o ngā momo paninga wai me te marara i roto i te peita kanapa me te peita haurua-kanapa. Ko te vinyl acetate, ngā esters acrylic, te styrene – he whakarewa kaha o ngā momo polymer acrylate, he wairewa iti (he iti iho i te tere mimiti wai, hei āwhina i ngā matūriki pupuhi), hei whakarite kia mimiti katoatia e ngā matūriki latex, he kiriata paninga tonu pai hei whakarato i te whakakotahitanga latex me te whanaketanga tae pai rawa atu, engari he pai hoki te pumau rokiroki. Ki te whakatauritea ki ngā tāpiringa hanga kiriata noa pēnei i te TEXANOL (ko te esters waipiro hanga-kāinga he -12), kua tino hangaia i roto i te kiriata, he kanapa tonu, he rere, he ārai-heke, he whanaketanga tae, i raro i te mirimiri me ētahi atu āhuatanga, ka whakaitihia e te PPH te nui o te 30-50%. He kaha te whakakotahitanga, he pai te whakauru i te 1.5-2 ngā wā, kua tino heke ngā utu whakaputa. Mō te nuinga o ngā whakapūhui, i tāpirihia e te PPH he nui o te 3.5-5% ki te whakapūhui, ā, ko te pāmahana hanga kiriata iti rawa (MFT) tae atu ki te -1°C.
Inenga
1. E taunaki ana kia tāpirihia te PPH i mua i te whakamomona, i te wā rānei e huri ana i te tae, kia māmā ai te hono i ngā whakatakotoranga PPH me ētahi atu kai, he pai ake kia whakamomonahia, kia marara hoki, ā, kia kore ai e pā ki te pumau o te tae me ērā atu mea pera.
2.I te nuinga o te wā, ko te nui o te tāpiri o te 3.5 ki te 6% o te whakaehu kiriaku, ko te nui o te 2.5-4.5% o te whakaehu kiriaku mō te winika i tāpirihia mō te styrene-kiriaku i te nuinga o te wā ko te 2-4%.
Mōkihi
200 kg /pahu, 25 kg /pahu kirihou rānei, kia rite ki ngā whakaritenga a te kiritaki.
Rokiroki
Ehara tēnei hua i te taonga mōrearea, me penapena ki te wāhi matao, maroke hoki.
