Ntchito ya latex ufa mumatope onyowa ndi matope pambuyo pochiritsa

Udindo wa ufa wa latex wopangidwanso muzomangamanga sungathe kuchepetsedwa. Monga zowonjezera zomwe zimagwiritsidwa ntchito kwambiri, tinganene kuti maonekedwe a ufa wa latex wotayika wakweza ubwino wa zomangamanga ndi mlingo umodzi. Chigawo chachikulu cha ufa wa latex ndi organic macromolecular polima wokhala ndi zinthu zokhazikika. Nthawi yomweyo, PVA imawonjezedwa ngati colloid yoteteza. Nthawi zambiri imakhala yaufa kutentha kwapakati. Kukhoza kumamatira ndi kolimba kwambiri ndipo ntchito yomanga ndi yabwino kwambiri. Kuonjezera apo, ufa wa latex uwu ukhoza kusintha kwambiri kukana kuvala ndi kuyamwa kwa madzi pakhoma powonjezera mphamvu yogwirizana ya matope. Panthawi imodzimodziyo, mphamvu zogwirizanitsa ndi zowonongeka ndizotsimikizika. digiri ya kuwongolera.

 

Udindo wa ufa wa latex wopangidwanso mumatope onyowa:

(1) Limbikitsani kusunga madzi mumatope;

(2) Wonjezerani nthawi yotsegula matope;

(3) Kupititsa patsogolo mgwirizano wamatope;

(4) Wonjezerani thixotropy ndi sag kukana matope;

(5) Kupititsa patsogolo kusungunuka kwamatope;

(6) Kupititsa patsogolo ntchito yomanga.

 

Udindo wa ufa wa latex wopangidwanso pambuyo pochiritsidwa matope:

(1) Wonjezerani mphamvu yopindika;

(2) Kupititsa patsogolo mphamvu zamanjenje;

(3) Kuwonjezeka kwa kusiyana;

(4) Kuchepetsa modulus ya elasticity;

(5) Kupititsa patsogolo mphamvu yolumikizana;

(6) Chepetsani kuya kwa carbonization;

(7) Wonjezerani kachulukidwe ka zinthu;

(8) Sinthani kukana kuvala;

(9) Chepetsani kuyamwa kwamadzi pazinthu;

(10) Pangani zinthuzo kukhala ndi zinthu zabwino zothamangitsira madzi.
