Take
Ko te PPP he waikawa maramarama me te kakara kakara kakara kakara. He maamaa-paitini me te taiao hoki hei whakaiti i te peita V ° he mea whakamiharo. Ka rite ki te maha o nga momo emulsion wai me te whakamaawhiawhi i te waikawa me te peita semi-grown he tino whai hua. He vinyl acetate acetate, styrene extters, styrne - stuvent solvent o nga momo ahumoana, he mea tino pai ki te whakatipu i te waikawa o Latex. I whakaritea ki nga taapiri whakaata-kiriata noa penei i Texanol (ALACE ACLADE ALMERS IS -12), he rite ki te papanga, he maamaa, he whanaketanga tae, he iti ake te rahi o te 30-50%. Te kaha o te kaha, te aukati i te kaha o te whakahekenga 1.5-2 nga wa, kua tino kaha nga utu whakaputa. Mo te nuinga o te whakahekenga, te pph i tapiritia ki te whakahekenga o te 3.5-5%, te iti o te pāmahana kiriata iti (MFT) o runga ake ki te -1 ° C.
Inenga
1. Ka tūtohu a PPP ki te taapiri i mua i te whakahekenga, te taapiri ranei i roto i te atamira hurihuri poaka, na reira kaore e pa ki te pumau o te poaka me te sex.
2.I roto i te katoa, ko te taapiri o te 3.5 ki te 6% te acrylin eculsin exullin mo te winika mo te nui o te 2.5-4.5% mo te ahua o Styrene-acrylic 2-4%.
