Iikomityi zeplastikiZizinto eziqhelekileyo ebomini bethu, sihlala sisebenzisa iikomityi zeplastiki ukuzalisa amanzi okanye iziselo. Kukho iintlobo ezininzi zeekomityi zeplastiki, ezinye iikomityi zeplastiki zinokuzaliswa ngamanzi ashushu, kodwa ezinye iikomityi zeplastiki zinokuzaliswa ngamanzi abandayo kuphela. Kwangaxeshanye, izinto ezahlukeneyo ziya kwahluka ngokubonakala. Ubomi esibusebenzisayo iikomityi zeplastiki zihlala zenziwe ngezinto zePP kunye nePET, abantu abaninzi baya kuba kwikomityi yeplastiki ngaba izinto zePP okanye izinto zePET zilungile kule ngxaki? Ngaba udidekile kule ngxaki, le makeup incinci ilandelayo ukuze ikuphendule, abahlobo abanomdla baya kudibana ngokukhawuleza ukuze bayibone!
I-PP yi-polypropylene, i-PET yi-polyester. Ngokwethiyori zombini azinabungozi, kodwa ngokwemeko yokwaluphala kunye nokumelana nemozulu, i-PP ifanelekile ngakumbi kwiikomityi zamanzi, i-PP inokumelana kakuhle nobushushu, inokumelana namaqondo obushushu aphezulu angama-120 degrees, yiplastiki kuphela enokufakwa kwi-microwave.
Ukusetyenziswa kwePolypropylene (PP): izitya ze-microwave, iimbiza, iibhakethi zeplastiki, amaqokobhe e-thermos, iingxowa ezilukiweyo, njl. Iimpawu: uzinzo oluphezulu lweekhemikhali, ukusebenza kakuhle kwempilo, ukumelana nobushushu obuphezulu. Izitya ze-microwave zingasetyenziswa iimveliso zeplastiki zePP eziphawulweyo. Ubuthi: abunabungozi, abunabungozi emzimbeni womntu. I-polymer inokuba nesakhiwo esinemilinganiselo emithathu: i-isometric, i-intergraphic, i-atactic polypropylene, ezimbini zokuqala zinokunyibilika, ezokugqibela azikwazi. Iimveliso ze-polypropylene ezithengiswayo ngokusisiseko zisakhiwo semarike ye-iso-gauge, iqondo lokunyibilika le-164 ~ 170 degrees Celsius, inxalenye yekristale yoxinano lwe-0.935 grams / cubic centimeters, inxalenye engacocekanga ye-0.851 grams / cubic centimeters. Ingxaki enkulu ye-PP kukuba kulula ukuyinyibilikisa kwaye iguge. Ngoku kongezwa kwee-antioxidants kunye nee-ultraviolet absorbers ukuze zoyiswe.
Ukusetyenziswa kwePolyester (PET): iibhotile zesiselo zeplastiki, iibhotile zamayeza, iibhotile zokuhombisa, iibhotile zeoyile, kunye neendidi ngeendidi zeebhotile, isigqubuthelo sobushushu. Iimpawu: ukucaca kakuhle, akukho lula ukuphula, uzinzo oluhle lweekhemikhali, lufanelekile kwiindidi ezahlukeneyo zokupakisha amayeza angamanzi okanye aqinileyo. Inesikhuseli esihle kwimitha ye-ultraviolet. Ubuthi: abunatyhefu.
Ibhotile yeplastiki yePET yeyona nto iphambili ekupakishweni kweziselo. Indawo ephambili kushishino lokupakisha iziselo eTshayina kufuneka ibe ziibhotile zeplastiki zePET, okwangoku, akukho zixhobo zibalaseleyo okanye ezingcono ezifunyenweyo zokutshintsha iibhotile zeplastiki zePET. Iibhotile zePP ikakhulu zi-one-step injection pull blowing kunye ne-two-step heating pull blowing, umatshini wokubumba kwi-PP bottles unezibonelelo zokuba zicacile, ziqinile, azitshisi ubushushu, kwaye ixabiso liphantsi kakhulu.
Iibhotile zeplastiki zePP ezinokumelana nobushushu okungcono, ukubonakaliswa kwemilo yebhotile kubuthathaka, ukhuseleko, ucoceko kunye nomxholo wencasa yokugcinwa kobuphantsi, ixabiso liphantsi kunePET, PS, PE kunye nezinye izinto. Iibhotile zeplastiki zePP kwimarike yokupakisha iziselo ekusebenziseni isikali ziye zasondela kancinci kancinci kwiibhotile zePET, iiresini eziguquliweyo, izithambisi zokungena, kunye nezakhono zoomatshini nezixhobo ngamanye amaxesha ukwenza uphuhliso lweekhonteyina zePP lunokutshintsha iikhonteyina zeglasi, zePET kunye nePVC, isabelo semarike siyakhula.
.
Izixhobo zePP kunye nePET zinezibonelelo kunye neempawu zazo, akukho nto ilungileyo okanye imbi ngokupheleleyo, ikakhulu kuxhomekeke kwiimfuno zomntu ngamnye kunye nokusetyenziswa kwemeko ukuze kugqitywe, ukuba zisetyenziswa rhoqo kumaqondo obushushu aphezulu, ungakhetha izixhobo zePP. Oku kungentla kuhlalutyo lwePP.iikomityi zeplastikikunye neekomityi zeplastiki zePET, ndiyathemba ukuba zinokukunceda.
