Uyini umehluko phakathi kwenjoloba yemvelo nenjoloba zokwenziwa?

Ukuqalisa

Irabha, impahla ebaluleke kakhulu kwizimboni zanamuhla, ngokuyinhloko ihlukaniswa ngezinhlobo ezimbili: Irabha yemvelo nerabha yokwenziwa. Lezi zinhlobo ezimbili ezihlukene zisebenza ezinhlobonhlobo zezicelo, ezivela kumathayi ezithuthi amadivaysi ezokwelapha, ngenxa yezakhiwo zazo ezihlukile. Ukuqonda umehluko phakathi kwenjoloba yemvelo nokwenziwa kubalulekile ekukhetheni okulungile kwezicelo ezithile.

Ukusukuma kwe Irabha yokwenziwa seliguqule izimboni ngokunikeza ezinye izindlela zenjoloba zemvelo, ikakhulukazi ezimweni lapho ukulinganiselwa kwendalo yemvelo, njengokuthambekela kokuguga nezimo zezemvelo, kubonakala. Lo mbhalo ukhipha umehluko phakathi kwalezi zinhlobo ezimbili zenjoloba, ehlola imvelaphi yazo, izakhiwo, izinhlelo zokusebenza, kanye nemithelela yezemvelo.

Irabha Yemvelo: Imvelaphi Nezakhiwo

Imvelaphi yenjoloba yemvelo

Irabha lemvelo lisuselwa ku-latex yezihlahla zenjoloba, ngokuyinhloko hevea brasiliensis. Leatex i-milky fluid ekhuphuka uchungechunge lwezinqubo, okubandakanya ukuhlangana nokusoma, ukukhiqiza irabha eluhlaza. Ukutshalwa kwezihlahla zenjoloba kugxilwe ezifundeni ezishisayo, namazwe afana neThailand, I-Indonesia, kanye neMalaysia ngokuba ngabakhiqizi abakhulu kunabo bonke.

Izakhiwo zenjoloba yemvelo

IRubber yemvelo idume ngobuhle bayo obuhle kakhulu, amandla aphezulu ashubile, kanye nokumelana nokugqoka nokuklebhula. Iphinde ikhombise futhi izakhiwo ezinhle zogesi zikagesi futhi zenze kahle ezindaweni zokushisa eziphansi. Kodwa-ke, kunomkhawulo, njengokumelana kabi nokushisa, ukukhanya, ne-ozone, okungaholela ekunciphiseni ngokuhamba kwesikhathi.

Injoloba zokwenziwa: Ukusungulwa kwanamuhla

Ukuthuthukiswa kwenjoloba yokwenziwa

Irabha yokwenziwa lakhiwa njengempendulo emikhawulweni yenjoloba yemvelo kanye nesidingo sezinto eziguquguqukayo. Injoloba yokuqala yokwenziwa, eyaziwa ngokuthi yiBuna, yadalwa ekuqaleni kwekhulu lama-20. Kusukela lapho, intuthuko yamakhemikhali we-polymer iholele ekuthuthukisweni kwezinhlobo ezahlukahlukene zenjoloba zokwenziwa, kufaka phakathi i-styrene-buthaene rubber (SBR), ne-NBR (NBR), ne-Ethdm).

Izakhiwo zenjoloba zokwenziwa

Irabha yokwenziwa linikeza izinzuzo eziningana ngaphezulu kwerabha yemvelo, njengokumelana okuthuthukile kokushisa, amakhemikhali nokuguga. Ingalinganiswa ukuze ihlangabezane nezidingo ezithile ngokuguqula ukwakheka kwayo kwamakhemikhali. Isibonelo, i-EPDM imelana kakhulu nesimo sezulu kanye ne-ozone, okwenza kube kuhle ngezicelo zangaphandle, ngenkathi i-NBR yaziwa ngokumelana kwamafutha amahle kakhulu.

Ukusebenza kwezicelo ezahlukahlukene

IRubber yemvelo isetshenziswa kabanzi kuzinhlelo zokusebenza ezidinga ukuqina okuphezulu kanye namandla ashubile, njengamathayi ezithuthi, amabhande okuhambisa, kanye nezicathulo zezinyawo. Ngakolunye uhlangothi, irabha yokwenziwa lithandwa ezindaweni lapho ukumelana khona lapho ukumelana nokushisa okwedlulele, amakhemikhali, noma ukuguga kubalulekile. Isibonelo, i-SBR ivame ukusetshenziswa emathayi emoto, kuyilapho i-silicone rubber isetshenziswa kumadivayisi wezokwelapha kanye nama-sains.

Umthelela wezemvelo

Ukukhiqizwa kwerabha yemvelo kunesisekelo esikhulu semvelo ngenxa yokuqothulwa kwamahlathi kanye nokusetshenziswa kwamakhemikhali kumasikhundla enjoloba. Injoloba zokwenziwa, ngenkathi inciphisa ukuncika kwimithombo yezemvelo, itholakala emikhiqizweni esekwe ephepheni, ukukhulisa ukukhathazeka mayelana nokukhishwa kwekhabhoni nokungeyona i-biodeGreadabilibility. Kwenziwa imizamo yokuthuthukisa ezinye izindlela ezizinzileyo, njenge-bio-based zokwenziwa kwerabha.

Ukugcina

Ekuphetheni, ukukhetha phakathi kwenjoloba yemvelo nokwenziwa kuncike kwizidingo ezithile zohlelo lokusebenza. Ngenkathi irabha yemvelo idlula emandleni ashubile, amandla ashubile, irabha yokwenziwa linikeza ukumelana okuphezulu ezicini zemvelo namakhemikhali. Ukuthuthuka okuqhubekayo kubuchwepheshe berabha kuyaqhubeka ukwandisa amathuba kuzo zombili izinhlobo zenjoloba, ukuqinisekisa ukuhambisana kwazo kwezimboni ezahlukahlukene.

Kulabo abanentshisekelo yokuhlola izinhlobo ezahlukahlukene zenjoloba zokwenziwa kanye nezicelo zabo, vakashela Injoloba zokwenziwa kwemininingwane enemininingwane.
