Ungayikhetha kanjani irabha efanele yephrojekthi ethile?

Ukuqalisa

IRubber yinto eguquguqukayo esetshenziswa kabanzi kuyo yonke imboni ehlukahlukene, kufaka phakathi izimoto, ukwakhiwa, ukunakekelwa kwempilo kanye nezimpahla zabathengi. Izakhiwo zayo ezihlukile, njengokuqina, ukuqina, kanye nokumelana namazinga okushisa aphezulu, kwenze kube yingxenye ebalulekile kuzinhlelo zokusebenza eziningi. Kodwa-ke, ukukhetha uhlobo olufanele lwenjoloba lwephrojekthi ethile kungaba ngumsebenzi owesabekayo ngenxa yohlu oluhlukahlukene lwezinketho ezitholakalayo. Lo mbhalo uhlose ukuhlinzeka umhlahlandlela ophelele wokuthi ungayikhetha kanjani irabha efanelekile yephrojekthi ethile, ucubungula izinto ezifana nezidingo zesicelo, izimo zemvelo, kanye nokusebenza kwezindleko. Ukuqonda okujulile kwezinhlelo zokusebenza ezahlukahlukene zenjoloba, vakashela Okokuhlikihla.

Ukuqonda Izinhlobo Zenjoloba

Irabha Yemvelo

Irabha yemvelo, ethathwe ku-latex yezihlahla zenjoloba, yaziwa ngobuqili bayo obuhle kakhulu, amandla ashubile, kanye nokumelana ne-abrasion. Isetshenziswa kakhulu kuzinhlelo zokusebenza ezinjengamathayi, izicathulo, kanye namabhande ezimboni. Kodwa-ke, irabha lemvelo linokulinganiselwa, kufaka phakathi ukumelana kabi nokushisa, ozone, kanye namafutha, okwenza kungakulungeli izindawo ezithile.

Zokwenziwa irabha

Irabha yokwenziwa lifaka izinhlobo ezahlukahlukene, ngayinye enezakhiwo ezihlukile ezenzelwe izinhlelo ezithile. Ezinye izinhlobo ezivame kakhulu zifaka:

• I-styrere-butdiene rubber (SBR): isetshenziswa kabanzi kumathayi ezithuthi namabhande ahambisa ngenxa yokumelana kwayo okuhle kwe-abrasion kanye nokusebenza kwezindleko.

• I-Ethylene Propellene Dieene Monomer (EPDM): Yaziwa ngokumelana kwayo okuhlukile kwesimo sezulu, i-Ozone, kanye nemisebe ye-UV, okwenza kube kuhle ngolwelwesi oluphahleni kanye nezicelo zangaphandle.

• I-FluoRoalastomers (FKM): Imelana kakhulu namakhemikhali, ukushisa kanye namafutha, esetshenziswa kakhulu e-aerospe kanye nezimpawu zezimoto.

• I-Chloroprene Rubber (CR): Inikeza isimo sezulu esihle kanye nokumelana kwe-ozone, kufanelekile ama-gaskets nama-hoses.

Izici okufanele zicatshangelwe lapho ukhetha irabha

Izidingo zohlelo lokusebenza

Isicelo okuhlosiwe kuyinto ebucayi ekukhetheni irabha efanele. Isibonelo, amathayi ezimoto adinga izinto zokwehluka okuphezulu nokuqina, kanti amadivaysi ezokwelapha angabeka phambili ukubekezelelana nokuvumelana nezimo. Ukuqonda izimfuno ezithile zephrojekthi yakho kuzosiza ukunciphisa phansi izinketho.

Izimo zezemvelo

Izici zezemvelo ezinjengokushisa, umswakama, nokuchayeka kumakhemikhali noma imisebe ye-UV inomthelela omkhulu ekusebenzeni kwerabha. Isibonelo, i-EPDM ilungele izinhlelo zokusebenza zangaphandle ngenxa yokumelana kwayo kwesimo sezulu, ngenkathi i-FKM ilungele kangcono izindawo ezinokuvezwa okuphezulu kwamakhemikhali.

Ukucatshangelwa Kwezindleko

Izingqinamba zesabelomali zivame ukudlala indima enkulu ekukhetheni kwezinto ezibonakalayo. Ngenkathi irabha yemvelo ngokuvamile ibiza kakhulu, amarubs okwenziwa afana ne-FKM ne-silicone anikela ukusebenza okuphezulu ezicelo ezikhethekile, evumela izindleko zawo eziphakeme.

Izinto ezintsha kubuchwepheshe benjoloba

Irabha eliqinile

Imboni iya ngokuya igxile emikhubeni eqhubekayo, njengokuthuthukisa ama-rubber asuselwa kwi-bio kanye nokuphinda usebenzise izinto zokwakha. Lezi ezintsha zihlose ukunciphisa umthelela wezemvelo wokukhiqizwa kwenjoloba nokulahlwa kwenjoloba.

Amasu athuthukile athuthukile

Amasu wesimanje ahlanganisiwe avumela ukwakheka ngokwezifiso zezakhiwo zenjoloba ukufeza izidingo ezithile. Isibonelo, engeza ama-fillers afana nekhabhoni emnyama yokuqina, kanti amapulasitiki athuthukisa ukuguquguquka.

Ukugcina

Ukukhetha irabha elifanele leprojekthi ethile kubandakanya ukuqonda okuphelele kwezinto ezibonakalayo, izidingo zohlelo lokusebenza, kanye nezimo zemvelo. Ngokubheka lezi zinto, ungaqinisekisa ukusebenza kahle kanye nokusebenza kwezindleko. Ukuthola okuthe xaxa kuzinhlelo zokusebenza zenjoloba kanye nezixazululo, hlola Okokuhlikihla.
