Foamed polyethylene. Pazinthu za nkhaniyi

Osati kale kwambiri msika wa pakhomo wa zipangizo zamatabwa, mungathe kuona zinthu zatsopano - zowonjezereka za polyethylene. Lili ndi makhalidwe apadera omwe alola kuti likhale lotchuka kwambiri. Anayamikiridwa ngati akatswiri mu bizinesi ya zomangamanga, ndi okonda kwambiri.

Amakonda bwanji?

Gulu la polyethylene la gululi limagwirizana bwino ndi ntchito zake monga zokopa ndi zolemba. Kawirikawiri, ntchito zoterezi ndizofunikira pamene zinthu zogulitsa zimakhazikitsidwa. Foamed polyethylene amapereka zowonjezera chitetezo kwa katunduyo kuchokera ku dothi, chinyezi ndi mawotchi amawononga. Pamodzi ndi izo, filimu yofiira ya mpweya imagwiritsidwa ntchito popititsa patsogolo chitetezo pamene kuli kofunikira.

Mbali za nkhaniyo ndi zosiyanasiyana

Kuti apange zinthu monga polyethylene yowonjezereka, poizoni amapangidwa kwa othylene wamba. Chifukwa cha ndondomekoyi, nkhaniyi imaphatikizapo pang'ono. Ndi chifukwa cha kukonzekera kwa maonekedwe kotero kuti zinthuzo zimakhala ndi chinyezi ngakhale madigiri 130, komanso zimatsutsa kusokonekera kwa chilengedwe.

Mitundu ya zinthu ndi thupi

Zomwe zimagwirizanitsidwa komanso zogwirizana ndi mankhwala - muyiyi, puloteni yowonjezera imaperekedwa kumsika wamakono. Ngati zimabwera pakapaka, ndiye kuti ndizofunikira kuti zikhale polyethylene, zisakanike thupi. Kutalika kwake kwa zosiyanasiyanazi kungakhale kosiyana ndi magawo asanu khumi ndi khumi mpaka makumi awiri. Ngakhale kuti kusiyana kwa kukula kwake kumakhala kochepa. Kotero wogula aliyense akhoza kukhala mwini wake wamapangidwe abwino, omwe amakwaniritsa zofunikira za munthu wina.

Ponena za zizindikiro za makhalidwe

Pali ziwerengero zambiri zomwe zimatsimikizira kutchuka kwa zinthu ngati poti polyethylene. Mtengo wa nkhaniyo umadalira mwachindunji khalidwe. Kotero, makhalidwe:

• Osati mankhwalawa, ndi otetezeka ku chilengedwe;
• Kuthazikika ndi kukhazikika;
• Kusasintha kwa kusintha kwa kutentha;
• Low abrasiveness;
• Zosangalatsa zozizwitsa katundu;
• Kutsutsana kwa deformation;
• Small thermal conductivity;
• Kusakaniza madzi;
• Kuthazikika, elasticity ndi elasticity.

Kwa makoswe oterowo ndi tizilombo sitikuvulaza. Mafangayi, nkhungu ndi zotsatira zake sizowopsa. Mapulogalamu otsekedwa otsegulidwa ndi chimodzi mwa zikuluzikulu za zinthu monga polyethylene chithovu. Kuchuluka kwa zinthuzo sikumakhudza luso lake labwino lokhala wotetezera bwino komanso luso loti asadutse chinyezi ndi nthunzi ngakhale zambiri. Ngati, poyikira pamwamba kapena paliponse pafupi ndi kugwa kwazale, ndi chithovu cha polyethylene chomwe chingatenge zinthu izi paokha. Choncho, mankhwalawo sangawonongeke kuti awonongeke.
