Ulwakhiwo olunokomelezwa kokumelana neekhemikhali, ukumelana nobushushu, kunye neempawu zoomatshini ziya kuphuhliswa ukuhlangabezana neemfuno ezibangwayo zemizi-mveliso eyahlukeneyo.
5. Ukwenziwa ngokwezifiso kunye nezisombululo eziKhethekileyo zeSicelo: Ngokwahluka kwezicelo kunye neemfuno zokudibanisa, ikamva le-polypropylene bonding adhesives liya kubandakanya ngakumbi ukwenza ngokwezifiso kunye nezisombululo ezilungiselelwe. Abavelisi be-Adhesive banokusebenzisana ngokusondeleyo nabathengi ukuphuhlisa iifomyula ezithile ezijongana nemiceli mngeni ekhethekileyo, bethathela ingqalelo ama-substrates, iimeko zokusingqongileyo, kunye neendlela zokusebenza ezinqwenelekayo. Izisombululo zokuncamathela ezenziwe ngokwezifiso zingakhokelela kwiinkqubo eziphuculweyo zokudibanisa kunye nokusebenza kwemveliso ephuculweyo.
6. Ukudityaniswa koBuchwephesha be-Smart: Ukudibanisa itekhnoloji entsha kwi-polypropylene encamathelayo yokuncamathelisa yindlela evelayo. Oku kunokubandakanya ukudibanisa imisebenzi efana neempawu zokuziphilisa, ukunyangwa okufunwayo, okanye izixhobo zoluvo ezizinzisiweyo zokujonga ingqibelelo yebhondi. Olu phuculo lunokuphucula ukuthembeka kunye nokusebenza kweendibano ezidityanisiweyo kwaye zenze kube lula ukubeka iliso kunye nokugcinwa kwexesha lokwenyani.

Njengoko imfuno esebenzayo kunye nethembekileyo yokuncamathelisa i-polypropylene ikhula, ishishini liya kungqina imathiriyeli, ulwakhiwo, kunye neendlela zokusebenzisa ukuqhubela phambili. Ngophando oluqhubekayo kunye nophuhliso, abavelisi banokuthi bajongane nemingeni ehambelana ne-polypropylene yokudibanisa kunye nokutyhala imida yetekhnoloji ye-adhesive, okukhokelela ekusebenzeni okuphuculweyo, ukunyuka kozinzo, kunye nokuphucula imveliso kwixesha elizayo.

isiphelo

I-Polypropylene bonding adhesives iye yaguqula indlela esijoyina ngayo i-polypropylene kunye nezinye ii-substrates kumashishini ahlukeneyo, kuquka iimoto, iimpahla zabathengi, ezonyango, i-electronics, ukwakhiwa, i-aerospace, kunye nolwandle. Iindidi ezahlukeneyo ze-polypropylene bonding adhesives zinika uluhlu lweenzuzo, kubandakanywa amandla aphezulu ebhondi, ukushisa kunye nokumelana nemichiza, ukusetyenziswa okulula kunye nokususwa, kunye neendleko eziphantsi. Ukukhetha i-adhesive efanelekileyo kwi-substrate kunye nesicelo siqinisekisa ibhondi ethembekileyo kunye nexesha elide. Njengoko uphando kunye neenzame zophuhliso ziqhubeka, sinokulindela ukuncamathela okungaphezulu kwe-polypropylene enikezela ukusebenza okuphezulu, ukuzinza, kunye nokuguquguquka. I-Polypropylene bonding adhesives isetelwe ukuba idlale indima ebaluleke kakhulu kwimveliso kunye neshishini, isenza sikwazi ukujoyina izinto ezahlukeneyo ngokufanelekileyo nangempumelelo.
