Wobwezeretsedwa polima ufa wowuma wosakanizira matope owonjezera

M'malo mwake msika, mitundu yosiyanasiyana ya ufa wa latex imatha kufotokozedwa kuti ndi yosalala. Zotsatira zake, ngati wogwiritsa ntchito alibe akatswiri ake aluso kapena zida zoyeserera, amatha kupusitsidwa ndi ogulitsa ambiri osachidziwa pamsika. Pakadali pano pali njira zina zodziwika bwino zomwe zimayenda pa intaneti, monga: kuona kuwonongeka kwa njira yosungunuka ndi mawonekedwe opanga mafilimu. Njirazi zimangochokera pansi, ndipo sizingapangitse kuthandizira kwa sayansi kwa sayansi kwa wogwiritsa ntchito kutsimikiza mtima kwa wogwiritsa ntchito kwa wogwiritsa ntchito kwa wogwiritsa ntchito kuti azolowere. Chifukwa chake, m'nkhaniyi, tichita mwatsatanetsatane mawonekedwe ena a mphira waufa kuchokera kuzomwe zimapangidwa ndi zinthu zoyambira, zomwe zimachitika, ndi cholinga chogwiritsa ntchito ufa wa mphira, kotero kuti ogwira nawo ntchito akhoza kudziweruza okha zabwino komanso zabwino. cholongosoka.

Choyamba, lingaliro lofunikira kuti mumvetsetse momwe ufa weniweni wa polima umapangidwira. (Obwezeretsedwanso ndi ufa wa polymer ndi katundu wosinthidwa omwe amasinthidwa kuchokera ku stunlsion ya sturlsion powonjezerapo ndi owuma polima, koma ochepa ali ndi ufa waposachedwa.) Aphatikizeponso: Polimer Remin, zowonjezera, kuteteza colloid, odana ndi anti-caking. 1. Pofuna kutsimikizira kukhazikika kwa malonda, mafakitale ambiri wamba nthawi zambiri amagwiritsa ntchito mtundu wa polyvinyl kuti apange polima ufa. Apa titha kutenga chitsanzo chothandiza. Mu 2015, mtundu wodziwika bwino wa mphira wanyumba yam'manja adasinthiratu polyvinyl emulsion kuti apange polima ufa chifukwa cha kuwongolera zifukwa zoyang'anira. Zotsatira zake, kusinthasintha kwakukulu kwapamwamba kunayambitsidwa. anachititsa kuti asawonongeke. Ngakhale amalonda ena achinyengo apa adzagwiritsa ntchito mochedwa ndi mafumbi.

2. Zowonjezera (zamkati) zimagwirira ntchito limodzi ndi ulesi kuti musinthe mawonekedwe, mwachitsanzo, pulasitiki yomwe imachepetsa kutentha kwa mafilimu (nthawi zambiri a vanyl acetate / ethyl Copymer (nthawi zambiri ma vinyl Ufa wokwezedwa wa opanga ochepa okha omwe amapanga njira yotentha ndipo sangatchulidwe kutentha kwagalasi, komwe kumakhalanso gawo lofunikira la mtundu wa mphira wa mphira womwewo.

3. Chitetezo cha Colloid wosanjikiza wa hydrophilic zinthu wokulungidwa pamwamba pa tinthu tating'onoting'ono tinthu tating'onoting'ono tofanana ndi tinthu tating'onoting'ono, ndipo thupi loteteza la ma ufa posachedwapa ndi mowa wa polyvinyl. Kuledzera kwa polyvinyl kuno ndi kutenga nawo mbali pakuwuma limodzi, m'malo mongophatikiza. Nayi vuto linanso pamsika. Ntchito zambiri zazing'ono zomwe zimati zimapangitsa kupanga ufa wa mphira kumangopanga kusakaniza kwakuthupi. Njirayi, izi sizingatchulidwe mosamalitsa ufa wobalalika.

4. Zowonjezera (zakunja) zowonjezeredwa kuti zikuwonjezeredwanso magwiridwe antchito a latex, monga kuwonjezera mphamvu zapamwamba za ufa waposachedwa. Monga zowonjezera zamkati, osati mtundu uliwonse wa ufa wobwezeretsedwayo umagwiritsidwa ntchito. Masamba a Masamba a Matebulo onse ali ndi zowonjezera izi.

5.. Filler iyi ndi gawo lomwe lidzawakhudza kwambiri kuti mukupanga mtengo weniweni ndi kufunikira kwa ufa wofatsa. Mafuta ambiri amtundu wa mphira pamsika amawonjezera kuchuluka kwa filler kuti muchepetse ndalama. Mwachidule, ndiye chizindikiritso cha phulusa lomwe limatchulidwa. Mafayilo osiyanasiyana owonjezeredwa ndi opanga osiyanasiyana amathanso kusakaniza ufa ndi simenti. Chifukwa kuluma kwa zomata zachilengedwe ku zida kumakwaniritsidwa kudzera pamakina ophatikizira
