Izinto ezi-5 eziqhelekileyo zeplastiki zokwenza ucingo kunye nentambo

Nangona iintlobo ze ucingokwaye intambozahlukahlukene, kodwa uninzi lwesakhiwo seemveliso ziyafana, izinto ezisetyenzisiweyo ziyafana, izinto eziqhelekileyo zokwenza izinto ziquka izinto eziqhubayo, izinto zokukhusela, izinto zokukhusela, izinto zokuzalisa, njl.njl., kunye ne-acIntamboUkuhambelana neempawu zazo ezahlukeneyo kunokwahlulwahlulwa zibe ziindidi ezimbini, izinto zesinyithi, ezifana ne-aluminium yobhedu, i-aluminium alloy, kunye nezinto zeplastiki. I-PVC eqhelekileyo, i-PE, i-PP, njl.njl., ezilandelwayo ziintlobo ezi-5 zezinto zeplastiki ezisetyenziswa rhoqo kwi-ucingokwaye intambo.

1. I-PVC, zezona zinto zeplastiki ezisetyenziswa kakhulu kwiingcingo kunye Intambo, I-PVC isetyenziswa ngokubanzi ekugqumeni ucingo kunye neentambo kunye nezinto zokukhusela, oku kungenxa yokuba i-PVC ineempawu ezininzi ezilungileyo zokukhusela ezinokuba lukhuselo oluhle lwangaphakathi lwentambo kunye neentambo, ezifana ne-PVC ayitshi lula, ukumelana nokwaluphala, ukumelana neoyile, ukumelana nokugqwala kweekhemikhali, ukumelana neempembelelo, Ezi mpawu zenza ukuba ibe nefuthe elihle lokuzihlukanisa kunye nokukhusela, ngoko ke izixhobo zokukhusela ngokubanzi zentambo kunye neentambo zizixhobo ze-PVC ikakhulu.

2. VULIWE(I-Polyethylene), uphawu lwayo lomzimba luyisakhiwo esimhlophe esikhanyayo njenge-wax, lunokuguquguquka okugqwesileyo, lunokolulwa ukuya kubude obuthile, lukhaphukhaphu kunamanzi, alunatyhefu, kodwa xa kuthelekiswa ne-PVC, i-polyethylene inophawu lokuba kulula ukuyitshisa. Nokuba iphuma emlilweni, iya kuhlala itsha, i-polyethylene ikwanazo iintlobo ezininzi ezandisiweyo, kubandakanya i-LDPE, i-MDPE, i-HDPE, i-LDPE yenye yezona zixinene ziphantsi, eyaziwa ngokuba yi-polyethylene ephantsi koxinzelelo, inokuguquguquka okuhle kakhulu. I-MDPE yi-polyethylene ephakathi koxinzelelo, eyaziwa ngokuba yi-polyethylene ephakathi koxinzelelo, ukusebenza kwayo kunye ne-polyethylene ephezulu kuyafana ngokusisiseko. I-HDPE ikwaziwa ngokuba yi-polyethylene ephezulu yoxinzelelo, ukusebenza kwayo okubanzi kuphezulu kakhulu, ngakumbi ukumelana nobushushu kunye namandla oomatshini zombini zenziwe ngcono. I-Polyethylene ineempawu zokufakelwa kombane ezibalaseleyo kwaye isetyenziswa kakhulu ekufakweni kweentambo zonxibelelwano.

3. I-EVA(i-ethylene - i-vinyl acetate copolymer), yi-thermoplastic efana nerabha, ukusebenza kwayo kunye nomxholo we-vinyl acetate (VA) kunobudlelwane obuhle, okukhona umxholo we-VA uncinci ufana ne-polyethylene, kokukhona umxholo uphezulu ufana neempawu zerabha, i-EVA inokuqina okuhle kunye nokumelana nobushushu obuphantsi, ukumelana neekhemikhali. Nangona ixutywe ne-LDPE, ingayiphucula ingxaki yokuba i-LDPE kulula ukuyiqhekeza, kwaye ukumelana nempembelelo, ukuthamba kunye nobunzima, kunye nokunamathela phakathi komqhubi kunye nokufakwa kwe-insulation kunokulungelelaniswa kakuhle kwaye komelezwe.

4. I-PP(I-Polypropylene), yeyona inenxalenye encinci phakathi kweeplastiki ezisetyenziswa rhoqo ngoku, amandla aphezulu oomatshini, ukumelana nobushushu obuphantsi, ukumelana nokwaluphala zingcono kakhulu, kunye namandla aphezulu okuqhekeka, iimpawu eziphantsi zokufunxa amanzi, izinto zePP zinokuba nobuchule kwindawo yezixhobo zokukhusela ezisetyenziswa rhoqo.

5. I-Polyester, olu hlobo lwezinto luphawulwa kukuxhathisa okukhulu ukukrazula, ukuguguleka okuphezulu, ukuthamba okuphezulu kunye ne-hysteresis ephantsi, umda ophezulu wobushushu obufanelekileyo ungafikelela kwi-1500 degrees Celsius, okungaphezulu kakhulu kunezinye irabha ze-thermoplastic, kodwa ikwanazo neempawu ezibalaseleyo zokuxhathisa ioyile kunye nokuxhathisa i-solvent.

UBoying yingcali intambo umboneleli oneqela elinamava, obonelela ngazo zonke iintlobo intambo kwaye intambo yokubophaUkuba ujonge intambo ekhethekileyo, I-Boying inesisombululo esenzelwe wena.
