Muva nje, uCalifornia wethula umbiko odonsele ukunakwa kwe-zinc onide nabakhiqizi besondo .
Kulomthetho omusha, iCalifornia incoma ukukhawulela ukusetshenziswa kwe-zinc noma i-zinc onide ngamathayi, futhi kungavimbela ukuthengiswa kwemikhiqizo yesondo equkethe i-zinc ethile equkethe i-zinc ethile .
I-zinc ingcolisa imvelo
I-US Bill ithi amanye ama-Zinc Alloys angafaka ubuthi ama-microorganisms kanye nezinto eziphilayo zasemanzini lapho i-zinc ikhishwa emvelweni nasemifuleni, imifula kanye nolwandle .
Ngokusho koMthethosivivinywa, izinto zenjoloba zangaphandle zingumthombo oyinhloko wokungcola kwe-zinc emvelweni .
Kuthiwa lo mthethosivivinywa ungadala umthetho ngekusasa ukunqabela abakhiqizi ukuthi bathengise noma bakhiqize amathayela emoto anokuqukethwe kwe-zinc edlula amaphesenti athile .
Ngaphansi koMthetho, abakhiqizi bangafaka izicelo eMnyangweni Wezinto Ezinobuthi Bendawo Ukulawula ukuthi babambezele ukukhishwa kwe-zinc-inhloso ekhethekile ye-zinc-equkethe izimoto ezivimba izimoto ezivimba izimoto .
Ngaphezu kwalokho, abakhiqizi babhekana nenhlawulo efinyelela ku- $ 10, {000 isikhathi ngasinye lapho bephula umthethosivivinywa .
Lo mthethosivivinywa uzokwazi uku-oda izikweletu zeToire Tervers ukuthuthukisa amafomu amasha, funa ezinye izindlela ezingaba khona kwi-zinc, futhi anqume ukuthi ezinye izindlela zizoba nomthelela empilweni yomphakathi nemvelo .
Abanye abakhiqizi be-zinc onide kanye nezinhlangano ezihlobene baphikisana nalo mthetho, basola imali ekhokhwayo ngokususelwa kumaphutha amazinga e-zinc emigwaqweni yamanzi amaningi .
Imithetho emisha ithinta izimboni ezimbili ezinkulu
Imboni ikholelwa ukuthi uma umthethosivivinywa udlulile, uzoba nomthelela omkhulu embonini yethayi .
Kufundwa ukuthi uhhafu we-zinc oxide okhiqizwayo ugelezela embonini yerabha, kanti imboni yethayi iyimakethe enkulu kunazo zonke ye-zinc onide .
I-Zinc noma i-zinc oxide isetshenziswa kakhulu njenge-catalyst enqubweni yeTire Vulcanization . Akuvimbisi kuphela amazinga we-Vulcanization, kodwa futhi kuthuthukisa ukuhambisa kabusha kwerabha futhi kusiza ukushiyeka kokushisa kwethayi .
Ngakho-ke, uma ukusetshenziswa kwe-zinc noma i-zinc onide kumathayi kukhawulelwe, noma ngabe ukusetshenziswa kuncishisiwe, kuzothinta ukuthuthukiswa kwesikhathi esizayo kwezimboni ezimbili .
Kuyaqondakala ukuthi njengamanje, imboni yamathayi asekhaya isasebenzisa inani elikhulu le-zinc onide, futhi izinkampani ezimbalwa zisebenzisa ezinye izindlela ezifanele ngokwengeziwe .
Ngasikhathi sinye, umthamo wokukhiqizwa wasekhaya we-zinc onide uhlinzekwa ngokweqile, futhi imakethe yethayi eliphansi sekwehlile eminyakeni emibili edlule, okuthe xaxa ukuncintisana kulo mkhakha . Kubikwa ukuthi isilinganiso samanje sokusebenza kwemboni singama-60% .
Ngokusho kokuhlaziywa, ukuncishiswa kokusetshenziswa kwe-zinc onide embonini yethayi kuyindlela enkulu yesikhathi esizayo . Ukungeniswa kwalo Mthethosivivinywa We-US .
