Q. Yintoni impahla ye-PPH
1. Izinto ze-Homopolymer polypropylene
Imathiriyeli ye-PPH yi-homopolymer polypropylene imathiriyeli elungiswe ngu-β, enokumelana neekhemikhali okugqwesileyo, ukumelana nobushushu obuphezulu, ukuxhathisa impembelelo, kunye nokuxhathisa okulungileyo kokuchwechwela. I-PPH (i-Polypropylene Homeo) imathiriyeli, eyaziwa ngokuba yi-homo polypropylene, ine-uniform kunye ne-eceke ye-beta crystal structure ngokuguqulwa kwe-β, ebonisa ukuxhathisa ukubola kweekhemikhali, ukuxhathisa kwe-abrasion, ukumelana nobushushu obuphezulu, ukuxhathisa ukubola, ukumelana nokuguga kunye nokugquma okulungileyo. Esi sixhobo asisetyenziswanga nje ngokubanzi kumashishini afana nobunjineli bekhemikhali, i-elektroniki, iifektri zamayeza, kunye nonyango lwamanzi amdaka, kodwa lukwanosetyenziso olubanzi kwiinkalo ezininzi ngenxa yeempawu zalo ezikhethekileyo zomzimba kunye neekhemikhali. Imibhobho yezinto ze-PPH kunye neepleyiti zenziwe kwizixhobo ezikwazi ukumelana nomhlwa kwaye zisetyenziswa ngokubanzi kwimimandla efana nobunjineli bemichiza, isinyithi, i-electronics, ibonakalisa ukusebenza kwayo okugqwesileyo kunye nexabiso lesicelo esibanzi.
I-2.Iimpawu eziphambili zezinto ze-PPH zibandakanya: Ukumelana nokushisa okugqwesileyo: ukukwazi ukujamelana neendawo zokushisa eziphezulu, ukugcina ukuzinza kwezinto kunye nokuqina.
Ukumelana noxinzelelo olulungileyo: ilungele ukusetyenziswa kwiindawo ezinoxinzelelo oluphezulu, ukuqinisekisa ukusebenza ngokukhuselekileyo kwenkqubo.
Ukumelana nemichiza: Inokumelana kakuhle nezinto ezahlukeneyo zeekhemikhali, ukwandisa ubomi benkonzo yezinto.
Ubomi obude: Ngenxa yokusebenza kakuhle okukhankanywe ngasentla, iimveliso ezenziwe ngezinto ze-PPH zinobomi obude benkonzo.
Ukongeza, imathiriyeli ye-PPH ikwanazo iingenelo zokungonakali, ukungaboli, kunye nokungakhuli, nto leyo eyenza ukuba isebenze kakhulu kwaye inoqoqosho kwiiprojekthi zofakelo lwemibhobho. Ngokubanzi, imathiriyeli ye-PPH idlala indima ebalulekileyo kwiinkalo zoshishino ezininzi ngenxa yetekhnoloji yohlengahlengiso ekhethekileyo kunye nokusebenza okugqwesileyo, ibonelela ngezisombululo ezithembekileyo kwizicelo ezahlukeneyo.
Q. Yintoni umahluko phakathi kwe-PPH kunye ne-PP
1. Kukho ukungafani okuphawulekayo phakathi kwe-PPH kunye ne-PP (i-polypropylene) ngokubhekiselele kwizinto eziphathekayo, iindawo zokusetyenziswa, iindlela zokucubungula, kunye neendleko. Iiyantlukwano eziphambili phakathi kwazo zezi zilandelayo: 1
Iimpawu zezinto eziphathekayo kunye nenkqubo yokuvelisa
I-PPH (i-polypropylene ye-homopolymer) yenziwe ngokuguqula ubunzima obuphezulu be-molecular, i-low melt flow rate i-homopolymer polypropylene ene-β, enokumelana okugqwesileyo kweekhemikhali, ukumelana nobushushu obuphezulu, kunye nokuxhathisa okulungileyo, kwaye ifanelekile kwiimeko ezinzima.
I-PP (i-polypropylene) ngokuqhelekileyo yenziwe nge-polypropylene random copolymer (RPP), enokumelana ne-corrosion efanelekileyo kwaye ifanele ukuthuthwa kweekhemikhali ngokubanzi.
2. Indawo yesicelo
I-PPH isoloko isetyenziswa kwiinkqubo zamanzi ashushu, amashishini ekhemikhali, kunye neendawo ezisingqongileyo ezifuna ubushushu obuphezulu kunye nokunganyangeki kwe-corrosion ngenxa yobushushu bayo obuphezulu kunye nokumelana neekhemikhali.
I-PP isetyenziswa kakhulu ekuthuthweni kolwelo oluneasidi kunye ne-alkaline kumashishini afana neekhemikhali, i-electroplating, kunye nokuprinta kunye nokudaya ngenxa yokumelana nokugqwesa kwayo okugqwesileyo.
Ukucubungula iteknoloji kunye nendlela yokudibanisa
Imibhobho ye-PPH ngokuqhelekileyo idibaniswe nge-welding, ukunyibilika okutshisayo, kunye nezinye iindlela, ezinamandla okudibanisa kunye nokusebenza kokutywinwa, kwaye zifanelekile kwiindawo ezinzima ezifana noxinzelelo oluphezulu kunye nokushisa okuphezulu.
Ukongeza kwi-welding kunye nokudibanisa okutshisa okunyibilikayo, imibhobho yePP inokudityaniswa kusetyenziswa iindlela ezahlukeneyo ezifana nokunyibilika kombane, okwenza kube lula kwaye kube lula.
3. Iindleko
I-PPH iyabiza kakhulu ngenxa yokumelana nokugqwesa kwayo okugqwesileyo kunye nokumelana nobushushu obuphezulu, kodwa ithandwa kakhulu kwezinye iiprojekthi ezifuna ukusebenza okuphezulu kwezinto.
I-PP inexabiso eliphantsi kwaye ifanelekile kwiiprojekthi ezifuna ukusebenza kakuhle koqoqosho.
Isishwankathelo, kukho ukungafani phakathi kwe-PPH kunye ne-PP ngokubhekiselele kwiipropati eziphathekayo, indawo yesicelo, ubuchule bokucubungula, kunye neendleko. Ukukhethwa kwezinto eziphathekayo kuxhomekeke kwiimfuno ezithile zesicelo kunye neemeko zokusingqongileyo.
