Tofauti na matumizi ya EPS, EPE, na EPP

Katika maisha yetu ya kila siku, tutaona maneno EPE, EPS, EPP, n.k. mara kwa mara. Kwa hivyo unajua nyenzo hizi ni nini? Ifuatayo, tutakuelekeza kuelewa nyenzo 3 za kawaida za ufungaji zinazotumika sokoni.

povu la EPS

Kwanza kabisa, kuingia mapema sokoni kwa vifungashio ni EPS, Expandable + Polystyrene = Expanded Polystyrene, au EPS kwa kifupi, jina rasmi la nyenzo hii ni polystyrene EPS. Uzito wake ni nyepesi zaidi kuliko nyenzo zingine. Hii huokoa gharama za nyenzo. Upungufu ni kwamba EPS inahitaji kuumbwa, ambayo inafaa kwa aina zote za vifungashio vyenye mahitaji makubwa na maumbo magumu. Kama unavyojua, mara tu ukungu unapoanzishwa, ikiwa unataka kubadilisha umbo, ni shida sana kurekebisha ukungu. Au ukibadilisha sana, hatuwezi kutumia ukungu wa asili tena. Katika enzi hii ya mabadiliko ya haraka, aina hii ya umbo lisilobadilika ni wazi kuwa haifai.

Moreover, EPS foam is white vacuum molding. The degradability of this material is very low, which has a great impact on the environment. Therefore, many countries that promote environmental protection are using EPS-återvinningsmaskiner to recycle EPS foam.

povu la EPE

EPE is officially known as Expanded Polyethylene. This material because it overcomes the shortcomings of ordinary styrofoam EPS fragile, deformation. It has many advantages such as water and moisture barrier, shockproof, sound insulation, heat preservation, and environmental protection. Also has good chemical resistance. Therefore it is an ideal substitute for traditional packaging materials. It is widely used in the packaging of many products such as electronic appliances, instruments and meters, computers, lighting, and so on.

Kwa kuongeza, inahitaji tu kukata na ukungu wa kisu kwa uundaji. Gharama ya uundaji wa uzalishaji ni ya chini kiasi. Kubadilisha mtindo ni rahisi kufanya. Hasara ni kwamba kiasi sawa cha nyenzo ni kizito na ghali zaidi kuliko EPS.

povu la EPP

Aina nyingine ya nyenzo za ufungaji ni EPP, ambayo inasimama kwa Polypropylene Iliyopanuliwa. Hii ni kifupi cha aina mpya ya povu, EPP ni povu ya plastiki ya polypropylene. Pia ni mchanganyiko wa polima ya fuwele yenye utendaji wa juu kiasi. EPP ni nyenzo inayofanana na EPS kwa upande wa uundaji na utendaji. Lakini utendaji wa nyenzo uko karibu na pamba ya lulu ya EPE, lakini ni bora kuliko unyumbufu wa EPS.

EPP pia ni nyenzo rafiki kwa mazingira ambayo inaweza kuchakatwa, inaweza kuharibika kiasili, na haitasababisha uchafuzi mweupe. Mara nyingi tunatumia nyenzo za EPP kwenye magari, kama vile viini vya bumper, vizuizi vya bumper, bitana za paa, vijazo vya milango, viti vya kichwa, vizuia jua, na kadhalika. EPP imetumika sana katika tasnia ya ufungaji, kama vile bidhaa za elektroniki, vifaa vya matibabu, n.k.
