Yintoni i-PP?
I-PP imfutshane kwiPolypropylene, i-polymoplastic polymer eyenziwe kwi-polymerition ye-proplenene monomer. Njengesixhobo esibalulekileyo seplastiki, i-PP inoluhlu olubanzi lwezicelo kubomi bemihla ngemihla kunye nokuvelisa imizi-mveliso. Kweli nqaku, siya kuhlalutya ngokweenkcukacha ukuba yintoni i-PP, kunye neempawu zayo, zisebenzisa kunye nezibonelelo.
Iimpawu ezisisiseko zeZixhobo zePP
Izinto ze-PP zinezinto ezibalaseleyo zomzimba kunye neekhemikhali. Ukuxinana kwayo kuphantsi, kuphela malunga ne-0.9 g / cm³, yeyona nto iphantsi kweplanga iqhelekileyo, ngoko ke inomzimba onobushushu. , kwaye uninzi lwee-acids, ialkalis kunye nezinyibilikisi zezinto eziphilayo zinokuchasa kakuhle. Ngenxa yezi zibonelelo, izinto ze-PP zibe lukhetho olufanelekileyo lwezinto ezininzi.
Ukwahlulahlulwa kunye nokuguqulwa kwezinto ze-PP
Izixhobo ze-PP zinokuhlelwa zibe ziziindidi ezimbini eziphambili, i-homopolymer polyproplene kunye ne-colyproplene ye-colyproplene, kuxhomekeke kwisakhiwo sabo semolekyuli kunye neepropathi. I-Homolly Polypropylene inobuqili obuphezulu kunye namandla, kuyenza ilungele iimveliso ezinobunzima obuphakathi, ngelixa i-colypyrproplene inezicelo ezifuna ukuxhaswa kwempembelelo ezingcono tshintshwa ngokongeza iintsinga zeglasi, i-mineral Fibles, okanye i-fildiaments, okanye ibhotile yokuphucula iipropathi zayo kunye nokungaxhathisi ubushushu, ukufezekisa iimfuno zoluhlu olubanzi lwezicelo. I-PP inokuguqulwa ngokongeza i-fibers yeglasi okanye i-Mineral Fillers okanye i-fildies ye-fildies yokuphucula iipropathi zayo kunye nokuxhathisa ubushushu ukuze kuhlangatyezwane noluhlu olubanzi lwezicelo.
Iindawo zesicelo sezinto zePP
Izinto ze-PP zinokufunyanwa kuyo yonke indawo ebomini, kwaye izicelo zabo zigubungela uluhlu olubanzi lwamabala, ukusuka kwizixhobo zokupakisha kunye neemveliso zasekhaya kwishishini lezithuthi kunye nezixhobo zonyango. Kwicandelo lokupakisha, izinto ze-PP zisetyenziswa ngokubanzi kwimveliso yezitya zokutya, ibhotile ye-Itland, iifilimu kunye nezinye iimveliso, ezingenambulelo kwaye zihambelana nemigangatho yokhuseleko lokutya. Kwimveliso yasekhaya, izinto ze-PP ziqhele ukwenza iibhokisi zokugcina, iibhasikithi zegumbi lokuhlambela, ifenitshala njalo njalo. Ngenxa yobushushu bayo obuhle kunye nokuxhathisa imichiza, i-PP ikwasetyenziswa kumzi-mveliso we-automotive ukwenza amaqhekeza, amatyala e-DEAshboard kunye neebhetri, njl. Njl.
Okuyisingqongileyo kwaye uzinzile
Kwiminyaka yakutshanje, njengoko ukwanda kokusingqongileyo kunyukile, izixhobo ze-PP zifumene ingqwalaselo ngakumbi ngenxa yokuphinda zisebenzise kwakhona kunye nefuthe elingaphantsi kwendalo. Izinto ze-PP zinokungcikiva ziphinde zisebenze kwakhona emva kokuchithwa, ukunciphisa ungcoliseko kwindalo esingqongileyo. Nangona izinto ze-PP azinakulinganiswa, ifuthe lokusingqongileyo linokuncitshiswa ngokufanelekileyo kulawulo lwenkunkuma yesayensi kunye nokurisayikilisha kwakhona. Ke ngoko, izinto ze-PP zithathwa njengento enobuhlobo bendalo kunye nendawo ezinzileyo yeplastiki.
Isishwankathelo
Izinto ze-PP zizinto zeplastiki ezihambahamba neziqendu ezibanzi zezicelo. Ukuxinana kwayo okuphezulu, ukumelana nobushushu, ukuxhathisa ubushushu, ukuxhathisa imichiza kunye nokuphinda ubugcisa kuye kwenza ukuba kwenye yezixhobo ezibalulekileyo kwishishini lemidlalo nobomi bemihla ngemihla. Ngokuqonda ukuba zeziphi izinto zePP kunye neendawo ezinokufunyanwa kuzo, unokusebenzisa ngcono izibonelelo zale nto ukubonelela ngekhephu elinokuthenjwa lokuyilwa kunye nokuveliswa kwazo zonke iintlobo zeemveliso.
