Chotsekera ndi chinthu chotsekera chomwe chimasinthasintha mawonekedwe a pamwamba pa chotsekera, sichimathamanga mosavuta, ndipo chimakhala ndi zomatira zinazake. Ndi guluu lomwe limagwiritsidwa ntchito kudzaza mipata pakati pa zinthu kuti ligwire ntchito yotsekera. Lili ndi ntchito zoletsa kutuluka kwa madzi, zosalowa madzi, zoletsa kugwedezeka, zoteteza mawu komanso zoteteza kutentha.
Kawirikawiri imachokera ku zinthu zouma kapena zosauma monga phula, utomoni wachilengedwe kapena utomoni wopangidwa, mphira wachilengedwe kapena mphira wopangidwa. Imapangidwa ndi zinthu zosadzaza monga talc, dongo, carbon black, titanium dioxide ndi asbestos, kenako ndikuwonjezera mapulasitiki, zosungunulira, zochiritsa, zothamangitsa, ndi zina zotero.
Kugawa kwa zomatira
Chotsekera chingagawidwe m'magulu atatu a chotsekera cholimba, chotsekera chamadzimadzi ndi mitundu itatu ya chotsekera chotsekera.
Malinga ndi gulu la mankhwala:Ikhoza kugawidwa m'magulu awiri: mtundu wa rabara, mtundu wa resin, mtundu wochokera ku mafuta ndi chosindikizira chachilengedwe cha polima. Njira yogawayi imatha kudziwa mawonekedwe a zinthu za polima, kudziwa kukana kutentha, kutseka, komanso kusinthasintha kuzinthu zosiyanasiyana.
Mtundu wa rabara:Mtundu uwu wa chosindikizira umachokera ku rabala. Ma rabala omwe amagwiritsidwa ntchito kwambiri ndi rabala ya polysulfide, rabala ya silicone, rabala ya polyurethane, rabala ya neoprene ndi rabala ya butyl.
Mtundu wa utomoni:Mtundu uwu wa sealant umachokera ku resin. Ma resin omwe amagwiritsidwa ntchito kwambiri ndi epoxy resin, unsaturated polyester resin, phenolic resin, polyacrylic resin, polyvinyl chloride resin, ndi zina zotero.
Zopangidwa ndi mafuta:Mtundu uwu wa chosindikizira umachokera ku mafuta. Mafuta omwe amagwiritsidwa ntchito kwambiri ndi mafuta osiyanasiyana a masamba monga mafuta a linseed, mafuta a castor ndi mafuta a tung, ndi mafuta a nyama monga mafuta a nsomba.
Kugawa malinga ndi ntchito:Ikhoza kugawidwa m'magulu awiri: kutentha kwambiri, kukana kuzizira, kupanikizika ndi zina zotero.
Kugawa malinga ndi mawonekedwe a filimu:Ikhoza kugawidwa m'magulu awiri: mtundu wouma womata, mtundu wouma womata, mtundu womata wosauma ndi mtundu wa viscoelastic wouma pang'ono.
Kugawa pogwiritsa ntchito:Ikhoza kugawidwa m'magulu otsekereza zomangamanga, otsekereza magalimoto, otsekereza kutchinjiriza, otsekereza ma CD, otsekereza migodi ndi mitundu ina.
Malinga ndi momwe ntchitoyo inayendera pambuyo pomanga:Ikhoza kugawidwa m'mitundu iwiri: chosungira chopopera ndi chosungira chopopera chocheperako. Pakati pawo, chosungira chopopera chingagawidwe m'magulu olimba komanso osinthasintha. Chosungira cholimba chimakhala cholimba pambuyo pa vulcanization kapena kulimba, ndipo nthawi zambiri chimakhala ndi kusinthasintha, sichingapindike, ndipo nthawi zambiri mipata singathe kusunthidwa; zosungira zosinthika zimakhala zotanuka komanso zofewa pambuyo pa vulcanization. Chosungira chosapopera ndi chosungira chofewa chomwe chimasungabe chogwirizira chosauma pambuyo pomanga ndipo chimasamuka mosalekeza kupita pamwamba.
