Poliyesitala ndi chiyani?

Poliyesitala ndi nthumwi wamba kalasi ya polyesters. Izi CHIKWANGWANI kupanga ku Sungunulani wa polyethylene terephthalate.

poliyesitala Kodi

pa maphunziro anali anayambitsa mu 1935 ku UK, izo m'kaundula mu 1945. Mu Soviet Union likutchedwa lavsan (pa malo kuphunzira mu Academy of Sciences Laboratory). Poliyesitala ndi chiyani? Zipangizo za gulu ntchito kupanga mafilimu chakudya, mapulasitiki. Ndi azimuth wamba makampani polima. Mu Russia, iwo ntchito makamaka ngati workpiece a mitundu yosiyanasiyana ya zomangamanga kwa mitundu yonse ya makontena a pulasitiki ndi chidebe. Pamlingo wamng'ono ntchito yopanga nsalu filimu ndi kuumba nkhani zosiyanasiyana. M'mayiko ena, zinthu zosiyana: kwambiri za terephthalate polyethylene ntchito kupanga yarns, ulusi.

kapangidwe

Poliyesitala ndi chiyani? Kodi mukudziwa ndi kapangidwe kake? Poliyesitala ali wapadera katundu. N'chifukwa chake kotero anayamikira. 100 poliyesitala akuzisunga wamphamvu kwambiri kutentha kukana. Iwo ali elasticity mkulu ndi otsika hygroscopicity. chuma ndi abwino ntchito makampani kuwala, chifukwa mankhwala amenewa kusunga maonekedwe kwambiri ndipo sasintha mawonekedwe. Pogwiritsa Ntchito ananena kuti poliyesitala kugonjetsedwa ndi kuchepa mphamvu, cinoni, iye sanali ngakhale mantha kupempha. Oyeretsa sikuloledwa.

A osakaniza ulusi ena

Kuonjezera mphamvu ya mankhwala kusasanyiwa, kuwapanga katundu antistatic, poliyesitala ntchito ndi ulusi zina zachilengedwe. kuphatikiza kwambiri bwino khalidwe la n'kumuuza ogula nsalu posoka mitundu yonse ya zovala (malaya, zamphepo, masuti ndi zovala zamkati kale). Popeza kuti poliyesitala zofewa ndiponso kupukuta mofulumira, nthawi zambiri pamodzi viscose ndi thonje. Poliyesitala CHIKWANGWANI zofanana kwambiri ndi ubweya, mwangwiro motengera kapangidwe CHIKWANGWANI achilengedwe. Izo ntchito zina, osakaniza ndi polyamide a. Kuyambira zina zosiyanasiyana yokhotakhota dongosolo, kukula ntchito poliyesitala CHIKWANGWANI akhoza kusintha kapangidwe ake, maonekedwe kukhala Mat kapena chonyezimira.

dera ntchito

Poliyesitala ndi chiyani? Atsegula gulu la nsalu angapange. Ndi wotchuka kwambiri ndipo ntchito kawirikawiri okonza. kukana ake zotsatira za kuunika, mphamvu yapamwamba, ndiponso chuma kusunga mawonekedwe kwa nthawi yaitali adzakhala mtengo zopangidwa kutsogolera mafashoni. Mbali zabwino zotsatirazi:

- woonda nsalu mofulumira kuyanika.

- kusamalidwa bwino ndi kupsa mawonekedwe si rumpled. Ziyenera adzanyamula kukumbukira kuti vuto la kutenthedwa mu makutu nsalu akhoza kuoneka kuti si mophweka kufalikira.

- Osati mantha dzuwa, saiwala, oyenera kusoka katundu nsalu. mankhwala amenewa kwa zaka zambiri ntchito, akuzisunga kuwala choyambirira cha mitundu.

- Easy yokonza, kugonjetsedwa Madontho, akaganizira lokha bwino kuti adzayeretsedwe.

- Mbali nsalu ya poliyesitala samuopa nyengo, abwino zida kusoka masewera, zovala, zamphepo.

- Pamene posoka mankhwala mwangwiro anasunga makutu zilimba zake ndi makwinya.

- Nsalu si anatambasula ndipo alibe kukhala, cholimba kumva kuwawa.

Wachisoni katundu wa poliyesitala ali motere:

- Low madzi mayamwidwe.

- kovuta banga.

- chawonjezeka chinthu chimodzimodzi, ndi inasangalatsa.
