Yintoni imathiriyeli yePP?
I-PP imfutshane kwi-Polypropylene, i-polymer ye-thermoplastic eyenziwe kwi-polymerisation ye-propylene monomer. Njengomathiriyeli obalulekileyo weplastiki, i-PP inoluhlu olubanzi lwezicelo kubomi bemihla ngemihla kunye nokuveliswa kwamashishini. Kweli nqaku, siya kuhlalutya ngokweenkcukacha ukuba yiyiphi impahla yePP, kunye neempawu zayo, ukusetyenziswa kunye neenzuzo.
Iimpawu eziphambili zezinto zePP
Izinto zePP zineempawu ezibalaseleyo zomzimba kunye neekhemikhali. Ubuninzi bayo buphantsi, kuphela malunga ne-0.9 g/cm³, yeyona nto iphantsi yoxinaniso lweeplastiki eziqhelekileyo, ngoko inobunzima obulula.PP ukumelana nobushushu bezinto eziphathekayo kunye nokumelana neekhemikhali nazo zilungile kakhulu, zingasetyenziswa kumaqondo obushushu angaphezu kwe-100 ° C ngaphandle kokuguqulwa. , kwaye uninzi lwee-asidi, i-alkali kunye ne-solvents ye-organic inokumelana nokugqwala okulungileyo. Ngenxa yolu ncedo, imathiriyeli yePP ibe lolona khetho lufanelekileyo lwemathiriyeli kwiinkalo ezininzi.
Ukuhlelwa kunye nokuguqulwa kwezinto zePP
Izinto zePP zingahlelwa kwiindidi ezimbini eziphambili, i-homopolymer polypropylene kunye ne-copolymer polypropylene, kuxhomekeke kwisakhiwo sabo se-molecular kunye neempawu. I-polypropylene ye-Homopolymer inokuqina okuphezulu kunye namandla, okwenza ukuba ilungele iimveliso ezineemfuno eziphezulu zobunzima, ngelixa i-polypropylene ye-copolymer inobunzima obungcono kunye namandla empembelelo ngenxa yokuqaliswa kweeyunithi ze-vinyl, kwaye isoloko isetyenziswa kwizicelo ezifuna ukumelana nempembelelo engcono.PP nayo ingakwazi iguqulwe ngokongeza iifayibha zeglasi, izihluzi zeminerali, okanye iiretardants zomlilo ukuphucula iimpawu zayo zomzimba kunye nokumelana nobushushu, ukuhlangabezana neemfuno zoluhlu olubanzi izicelo. I-PP inokuguqulwa ngokongeza iifayili zeglasi okanye iifayili zamaminerali okanye i-flame retardants ukuphucula iimpawu zayo ezibonakalayo kunye nokumelana nokushisa ukuhlangabezana noluhlu olubanzi lwezicelo.
Iindawo zokusetyenziswa kwemathiriyeli yePP
Izinto zePP zinokufumaneka kuyo yonke indawo ebomini, kwaye izicelo zabo zigubungela uluhlu olubanzi lweenkalo, ukusuka kwizinto zokupakisha kunye neemveliso zendlu ukuya kwishishini leemoto kunye nezixhobo zonyango. Kwintsimi yokupakisha, izinto zePP zisetyenziswa ngokubanzi ekuveliseni izitya zokutya, iibhotile zebhotile zesiselo, iifilimu kunye nezinye iimveliso, ezithandwayo ngenxa yokuba zingenabuthi, zingenancasa kwaye zihambelana nemigangatho yokhuseleko lokutya. Kwiimveliso zendlu, izinto zePP zisetyenziswa ngokuqhelekileyo ukwenza iibhokisi zokugcina iimpahla, iibhasikithi zokuhlamba iimpahla, ifenitshala kunye nokunye. Ngenxa yokushisa kwayo okulungileyo kunye nokuchasana kweekhemikhali, i-PP iphinda isetyenziswe kwishishini leemoto ukwenza i-bumpers, i-dashboards kunye neemeko zebhetri, njl njl. I-PP iphinda isetyenziswe ngokubanzi kwintsimi yezonyango, njengeesirinji ezilahlayo, iibhotile ze-infusion kunye nezixhobo zokuhlinzwa.
Ihambelana nendalo kwaye iZinzile
Kwiminyaka yakutshanje, njengoko ulwazi lokusingqongileyo lunyukile, izixhobo zePP zifumene ingqwalasela engaphezulu ngenxa yokuphinda zisetyenziswe kunye nefuthe eliphantsi lokusingqongileyo. Imathiriyeli yePP inokuphinda ihlaziywe ngokuphinda isetyenziswe emva kokulahlwa, ukunciphisa ungcoliseko kokusingqongileyo. Nangona imathiriyeli yePP ingonakali, impembelelo yayo yokusingqongileyo inokucuthwa ngokusebenzayo ngolawulo lwenkunkuma yenzululwazi kunye nokurisayikilisha. Ke ngoko, imathiriyeli yePP ithathwa njengento ehambelana nokusingqongileyo kunye nezixhobo zeplastiki ezizinzileyo.
Isishwankathelo
Izinto zePP zizinto zeplastiki eziguquguqukayo ezinoluhlu olubanzi lwezicelo. Ubuninzi bayo obuphantsi, ukumelana nobushushu, ukuxhathisa imichiza kunye nokuphinda kusetyenziswe kwakhona kuyenza enye yezinto eziyimfuneko kwishishini lanamhlanje kunye nobomi bemihla ngemihla. Ngokuqonda ukuba yintoni impahla yePP kunye neendawo zayo zokusetyenziswa, ungasebenzisa ngcono izibonelelo zalo mbandela ukubonelela ngenketho ethembekileyo yoyilo kunye nokuveliswa kwazo zonke iintlobo zeemveliso.
