Yintoni iFilimu yePolypropylene Overwrap ejongene neBiaxial Oriented?
Ifilimu ye-polypropylene (BOPP) ejongeka kwi-Biaxially luhlobo lwefilimu yokupakisha eguquguqukayo. Ifilimu ye-polypropylene ejongeka kwi-Biaxially yolulwe kwiindlela zomatshini kunye nezinqamlezileyo. Oku kubangela ukujongwa kwe-molecular chain kuzo zombini iindlela. Olu hlobo lwefilimu yokupakisha eguquguqukayo lwenziwa ngenkqubo yokuvelisa ityhubhu. Iqamza lefilimu elimile okwetyhubhu liyafuthwa kwaye lifudunyezwe lifikelele kwinqanaba lalo lokuthamba (oku kwahlukile kwinqanaba lokunyibilika) kwaye lolulwe ngoomatshini. Ifilimu yolulwe phakathi kwe-300% - 400%. Kungenjalo, ifilimu inokolulwa ngenkqubo eyaziwa ngokuba yi-tenter-frame film manufacturing. Ngale ndlela, iipolymers zikhutshelwa kwi-cooled cast roll (eyaziwa ngokuba yi-base sheet) kwaye zitsalwe kwicala lomatshini. Ifilimu ye-tenter-frame manufacturing us... -

Iintlobo ze-polypropylene.
Iimolekyuli zePolypropylene ziqulathe amaqela e-methyl, anokwahlulwa abe yi-isotactic polypropylene, i-atactic polypropylene kunye ne-syndiotactic polypropylene ngokwendlela amaqela e-methyl ahlelwe ngayo. Xa amaqela e-methyl ebekwe kwicala elinye le-main chain, ibizwa ngokuba yi-isotactic polypropylene; ukuba amaqela e-methyl asasazwa ngokungacwangciswanga kumacala omabini e-main chain, ibizwa ngokuba yi-atactic polypropylene; xa amaqela e-methyl ebekwe ngokwahlukeneyo kumacala omabini e-main chain, ibizwa ngokuba yi-syndiotactic. polypropylene. Kwimveliso ngokubanzi ye-polypropylene resin, umxholo wesakhiwo se-isotactic (esibizwa ngokuba yi-isotacticity) umalunga ne-95%, kwaye okuseleyo yi-atactic okanye i-syndiotactic polypropylene. I-polypropylene resin eyenziwayo ngoku eTshayina ihlelwe ngokwe... -
Ukusetyenziswa kwe-resin ye-pvc yokuncamathisela.
Kuqikelelwa ukuba ngo-2000, ukusetyenziswa okupheleleyo kwemarike ye-PVC paste resin yehlabathi bekumalunga ne-1.66 yezigidi zeetoni. E-China, i-PVC paste resin ikakhulu inezicelo ezilandelayo: Ishishini lesikhumba sokwenziwa: ukubonelela ngemarike iyonke kunye nokulinganisela kwemfuno.

UChemdo uceba ukuthatha inxaxheba kwimiboniso kulo nyaka.
IChemdo iceba ukuthatha inxaxheba kwimiboniso yasekhaya neyangaphandle kulo nyaka. Ngomhla we-16 kuFebruwari, abaphathi bemveliso ababini bamenywa ukuba baye kwikhosi eququzelelwe yiMade in China. Umxholo wale khosi yindlela entsha yokudibanisa ukukhuthazwa ngaphandle kwe-intanethi kunye nokukhuthazwa kwi-intanethi kwamashishini orhwebo lwangaphandle. Umxholo wekhosi ubandakanya umsebenzi wokulungiselela ngaphambi komboniso, amanqaku aphambili okuxoxisana ngexesha lomboniso kunye nokulandelelana kwabathengi emva komboniso. Sinethemba lokuba abaphathi ababini baya kuzuza lukhulu kwaye bakhuthaze inkqubela phambili egudileyo yomsebenzi womboniso olandelayo.
