Wobwezeretsedwa Polider ufa mu matope

Ufa wobwezeretsedwa polima nthawi zambiri umawonedwa pomanga ngati zinthu zakunja zakunja. Zimakhala zopangidwa ndi polystyrene tinthu ta polystyrene ndi polimame, motero amatchedwa chifukwa chake. Mtundu wamtunduwu polima umapangidwa makamaka chifukwa cha kuchuluka kwa polystyreene. Matope polymer ufa ali ndi zomatira bwino, katundu wopanga mafilimu, kukana ndi nyengo ndi kukhazikika kwamankhwala.

Kusiyanasiyana kwa ntchito zamtondowobwezeredwapolymerpawudaAmazindikiranso kuti ntchito yake imakhala yochulukirapo. Nthawi zambiri imagwiritsidwa ntchito potuta yakunja kapena yamkati ya zokutira zakunja monga makoma akunja, matabwa a polystyrene, ndi matabwa otalika. Wophimba ufa wa ufa wa matope amatha kugwiritsa ntchito bwino kwambiri madzi osavala madzi, moto wamoto komanso kuteteza kutentha.

Kodi mapangidwe ake akumanga matope ndi polymer ndi ati? Ndiloleni ndikambirane mwachidule za mfundo zitatu:

1. Tiyenera kuyeretsa fumbi pakhoma loyambirira kuti nthaka ikhale yoyera komanso yabwino;

2. Chigawo chosinthachi ndi monga momwe mungatsatire: madzi = 1: 0.3, titha kugwiritsa ntchito chosakanizira matope osakanikirana;

3. Titha kugwiritsa ntchito phala kapena njira yopyapyala kuti tiyike khomalo, kuti mugonjetse kulowereka kwina;

Zambiri mwatsatanetsatane, mutha kuyang'ana:

1. Ndiwo matenda oyambira ufa. Tiyenera kuwonetsetsa kuti malo osokoneza bongo oti apangidwidwe ndi osalala komanso olimba. Ngati ndi kotheka, imatha kupukutidwa ndi sanspaper yamasamba. Pakadali pano, ziyenera kudziwika kuti gulu losasunthika liyenera kuphatikizidwa mwamphamvu, ndipo ma seams omwe angathe kukwera ndi kusokonezeka ndi kusokonezeka kwa nthaka ndi polymer ufa wa matope anu;

2. Pamene tikhazikitsa ufa wa matope, tifunika kuwonjezera madzi mwachindunji, kenako nkuwayambitsa kwa mphindi 5 isanagwiritsidwe;

3. Pomanga ufa wa matope, tiyenera kugwiritsa ntchito chiuno chachitsulo chosapanga dzimbiri pa gulu lotsutsa, kanikizani nsalu ya galasi la matope a gypsum ndikupangitsa kukhala kosalala. Chinsalu cha mesh iyenera kulumikizidwa ndikudumphidwa kwambiri. M'lifupi nsalu yagalasi ndi 10cm, nsalu yagalasi imafunikira kuphatikizidwa kwathunthu, ndipo makulidwe a chiberekero cholimbikitsidwa kumtunda ndi 2 ~ 5cm.

Matope polymer ufa ndi malo omaliza atatha kuwonjezera polymer ufa. Kutsutsana kwake kungakhale kolimba, komwe kumatha kulepheretsa kukokoloka kwa acidic mlengalenga, ndipo sizophweka kuyika komanso kutsutsana ngakhale mutakhala onyowa. Pa khomalo ndi kunja kwa khoma.
