Resin makamaka imatanthauza chinthu chachilengedwe chomwe chimakhala cholimba, cholimba pang'ono kapena cholimba pseudo-solid kutentha kwa chipinda, ndipo nthawi zambiri chimakhala ndi kufewa kapena kusungunuka chikatenthedwa. Chikafewa, chimakhudzidwa ndi mphamvu zakunja ndipo nthawi zambiri chimakhala ndi chizolowezi choyenda. Mwachidule, kodi ma polima monga matrix apulasitiki onse angakhale ma resin?

Pulasitiki imatanthauza zinthu zopangidwa ndi polima zachilengedwe zopangidwa ndi kuumbidwa ndi kukonzedwa ndi utomoni ngati gawo lalikulu, kuwonjezera zowonjezera zina kapena zinthu zina zothandizira.

Mitundu yodziwika bwino ya mapulasitiki:

Mapulasitiki wamba: polyethylene, polyvinyl chloride, polystyrene, polymethylmethacrylate.

Mapulasitiki aukadaulo wamba: polyester amine, polycarbonate, polyoxymethylene, polyethylene terephthalate, polybutylene terephthalate, polyphenylene ether kapena modified polyphenylene ether, ndi zina zotero.

Mapulasitiki apadera aukadaulo: polytetrafluoroethylene, polyphenylene sulfide, polyimide, polysulfone, polyketone ndi polymer yamadzimadzi a kristalo.

Mapulasitiki ogwira ntchito: mapulasitiki oyendetsera magetsi, mapulasitiki a piezoelectric, mapulasitiki a maginito, ulusi wa pulasitiki wowunikira ndi mapulasitiki owunikira, ndi zina zotero.

Mapulasitiki okhazikika a thermosetting: phenolic resin, epoxy resin, unsaturated polyurethane, silicone ndi amino plastic, ndi zina zotero.

Masipuni apulasitiki, chimodzi mwa zinthu zathu zazikulu zapulasitiki, chimakonzedwa kuchokera ku zipangizo zopangira chakudya za PP.ma funnel apulasitiki, ndodo zopumira m'mphuno, zinthu zonse zachipatala kapena za m'ma laboratories kapena ziwiya za m'khitchini zapakhomo nazonso ndi zinthu zopangira chakudya.

Malo ogwiritsira ntchito pulasitiki:

1. Zipangizo zopakira. Zipangizo zopakira ndi zomwe zimagwiritsidwa ntchito kwambiri ndi pulasitiki, zomwe zimapangitsa kuti zikhale zoposa 20% ya zonse. Zinthu zazikuluzikulu zimagawidwa m'magulu awa:

(1) Zinthu zopangidwa ndi filimu, monga filimu yopepuka komanso yolemera yolongedza, filimu yotchinga, filimu yotenthetsera kutentha, filimu yodzimatira yokha, filimu yoletsa dzimbiri, filimu yong'ambika, filimu yopukutira mpweya, ndi zina zotero.

(2) Zinthu zopangidwa m'mabotolo, monga mabotolo ophikira chakudya (mafuta, mowa, soda, vinyo woyera, viniga, soya msuzi, ndi zina zotero), mabotolo odzola, mabotolo a mankhwala ndi mabotolo ogwiritsira ntchito mankhwala.

(3) Zinthu zogulitsidwa m'mabokosi, monga mabokosi azakudya, zida, ntchito zamanja, zinthu zachikhalidwe ndi maphunziro, ndi zina zotero.

(4) Zinthu zopangidwa ndi makapu, monga makapu a zakumwa zotayidwa, makapu a mkaka, makapu a yogati, ndi zina zotero.

(5) Zinthu zogulitsidwa m'mabokosi, monga mabokosi a mowa, mabokosi a soda, mabokosi azakudya

(6) Zinthu zogulira matumba, monga zikwama zam'manja ndi matumba oluka

2. Zofunikira za tsiku ndi tsiku

(1) Zinthu zosiyanasiyana, monga mabeseni, migolo, mabokosi, mabasiketi, mbale, mipando, ndi zina zotero.

(2) Zinthu zachikhalidwe ndi zamasewera, monga mapeni, ma rula, badminton, tenisi ya patebulo, ndi zina zotero.

(3) Chakudya cha zovala, monga nsapato, chikopa chochita kupanga, chikopa chochita kupanga, mabatani, mapini a tsitsi, ndi zina zotero.

(4) Zinthu zakukhitchini, monga masipuni, matabwa odulira, mafoloko, ndi zina zotero.

Ndi zimenezo lero, tidzaonananso nthawi ina.
