Intshayelelo kwimveliso yeplastiki yekhaya

2021/01/20

Iiplastikhi yimixube yepolymer, eyaziwa ngokuba ziiplastikhi okanye ii-resin, ezifakwe ipolymer ngokudityaniswa okanye ukuncitshiswa kwee-monomers njengezinto ezisetyenzisiweyo. Banokutshintsha ngokukhululekileyo ukwakheka kunye nemilo. Zenziwe ngee-resins zokwenziwa, iifillers, i-plasticizers, i-stabilizers, i-lubricants, i-colorants kunye nezinye izongezo.

IPolyethylene terephthalate (PET)

Amanzi amaminerali ngokubanzi kunye neebhotile zesiselo sekhabhon zenziwe nge-polyethylene terephthalate (PET), ngo-1946, i-United Kingdom yapapasha ilungelo elilodwa lomenzi lokulungiselela i-PET. Ngo-1949, ifomula yase-Bhritane ye-ICI yagqiba uvavanyo lokulinga, kodwa emva kokuba i-United States iDuPont Inkampani ithenge ilungelo lobunikazi, isixhobo semveliso sasekwa ngo-1953, kwaye imveliso yokuqala yezorhwebo yafezekiswa emhlabeni.

Izinto eziluncedo:

1, ukumelana neoyile, ukuxhathisa amafutha, i-enic acid, ukuxhathisa ukumelana nealkali, uninzi lwezinyibilikisi.

2, ukungafihli okuphezulu, ukuhanjiswa kokukhanya kunokufikelela ngaphezulu kwe-90%, iimpahla ezihlanganisiweyo zinomsebenzi olungileyo wokubonisa.

I-3, inokumelana nobushushu obuphantsi kakhulu, inokumelana -30â „ƒ ubushushu obuphantsi, kuluhlu lwe - 30â„ ƒ-60â „ƒ ukusetyenziswa.

4, irhasi kunye nokungena komphunga wamanzi kusezantsi, zombini ukuxhathisa igesi, amanzi, ioyile kunye nokusebenza kwevumba elikhethekileyo.

5, elubala eliphezulu, ukuvimba ukukhanya yelanga, kubengezela elungileyo.

Amanqaku okusetyenziswa:

Iibhotile zesiselo azinakuphinda zisebenze kwakhona ngamanzi ashushu, obu bushushu bunokumelana ne-70â „ƒ, iqondo lobushushu eliphezulu liya kunyibilika izinto eziyingozi, ezifanelekileyo kuphela iziselo ezishushu okanye iziselo ezibandayo, ulwelo lobushushu obuphezulu okanye ukufudumeza kulula ukukhubazeka, kukho izinto eziyingozi umzimba womntu wanyibilika.
