Cholimbitsa Kutentha Chophatikizana

Zokhazikika za mchere wa lead sizimangokhala ndi kutentha kwabwino komanso zitha kugwiritsidwa ntchito ngati chokhazikika chachikulu cha PVC pazinthu za PVC, komanso zimakhala ndi mawonekedwe awoawo, omwe amafunika kusamalidwa mukamagwiritsa ntchito. Malinga ndi zaka zambiri zaukadaulo wopanga fomula, mfundo zomwe ziyenera kusamalidwa mukamagwiritsa ntchito monomeric lead salt stabilizers zafupikitsidwa motere:

1. Kumvetsetsa bwino makhalidwe ndi nthawi zomwe zimagwiritsidwa ntchito pa lead salt composite stabilizer iliyonse, ndikuyesa ndikukonza pogwiritsa ntchito.

Chokhazikika chilichonse cha mchere wa lead chili ndi makhalidwe akeake komanso mtundu wake wogwiritsira ntchito. Ngati tikufuna kugwiritsa ntchito bwino chokhazikika, tiyenera kumvetsetsa bwino makhalidwe ake, kudziwa momwe chingasonyezere ubwino wake, komanso momwe zinthu siziyenera kugwiritsidwa ntchito. Mwachitsanzo, dibasic lead phosphite ili ndi kukana kwabwino kwa nyengo, ndipo ubwino wake ungagwiritsidwe ntchito mokwanira pazinthu zakunja zomwe zimagogomezera kukana kwa nyengo, kotero nthawi zambiri imagwira ntchito ngati chokhazikika chachikulu pazinthu zotere, pomwe tribasic lead sulfate ili ndi magwiridwe antchito abwino kwambiri pakukhazikika kwa kutentha, ingagwiritsidwe ntchito ngati chokhazikika chachikulu pakakhala kufunikira kukhazikika kwa kutentha kwambiri.

2. Sankhani chokhazikika choyenera malinga ndi momwe zinthu zilili komanso momwe zimagwiritsidwira ntchito

Zinthu zosiyanasiyana zimakhala ndi zofunikira zosiyanasiyana, ndipo zinthu zosiyanasiyana zokhazikika ziyenera kusankhidwa. Zipangizo zosiyanasiyana ndi zinthu zosiyanasiyana zogwirira ntchito zimakhala ndi zofunikira zosiyanasiyana zokhazikika. Timaganizira mosamala momwe zinthu zimagwiritsidwira ntchito popanga kapangidwe kake ndikusankha mtundu woyenera wa zinthu zokhazikika komanso kuphatikiza. Mlingo. Pakati pa zinthu zazikulu, mapaipi nthawi zambiri safuna kukana nyengo, kotero tribasic lead sulfate yokhala ndi kukhazikika kwabwino kwa kutentha imagwiritsidwa ntchito makamaka ngati chokhazikika chachikulu. Kuphatikiza apo, chifukwa cha mawonekedwe osavuta a chitoliro komanso mbiri yochepa ya kutentha panthawi yokonza, kuchuluka kwa chokhazikika sikokulirapo kwambiri.

3. Mphamvu yogwirizana pakati pa okhazikika

Pali zotsatira zitatu zosiyana za kuphatikiza kwa okhazikika: chimodzi ndi mphamvu yogwirizana, yomwe ndi mphamvu ya 1+1>2; china ndi mphamvu yowonjezera, yomwe ndi mphamvu ya 1+1=2; china ndi mphamvu yotsutsana, yomwe ndi mphamvu ya 1+1<2. Tiyenera kumvetsetsa bwino momwe zinthu zosiyanasiyana zimagwirira ntchito popanga kapangidwe kake, kugwiritsa ntchito mphamvu yogwirizana pakati pa okhazikika, ndikuyesetsa kupewa mphamvu yolimbana pakati pa okhazikika, kuti tipeze njira yochepetsera kutentha yotsika mtengo.
