Amashidi enjoloba abalulekile ezimbonini zonkana, futhi ukusetshenziswa kwawo kuchazwa ukwakheka kwezinto ezibalulekile. Kusukela kunjoloba yemvelo kuye kuma-synthetics athuthukisiwe kanye nokwahluka okugaywe kabusha, uhlobo ngalunye lunikeza izici zokusebenza ezihlukile eziklanyelwe izimo ezithile zokusetshenziswa, okwenza ukukhetha kwezinto ezibalulekile kube semqoka ekusebenzeni kahle nokusebenza isikhathi eside. Ngezansi kukhona incazelo enemininingwane yezinto ezivamile zeshidi lerabha, izakhiwo zazo, izinhlelo zokusebenza, neziqhathaniso zokusebenza ezibalulekile.
Izinto Ezibalulekile Zeshidi Lerabha: Izakhiwo Nezicelo
1. Amashidi Erabha Yemvelo (NR).
Asuselwe ku-latex yezihlahla zenjoloba, amashidi e-NR aziswa ngokunwebeka okukhethekile (ubude obufika ku-800%), amandla aqinile aphezulu, nokuqina okuphakeme. Zisebenza kahle emazingeni okushisa aphakathi nendawo (-50°C kuya ku-80°C) kodwa zisengozini kawoyela, i-ozone, nemisebe ye-UV.
- Izicelo: Imishini ejwayelekile yokukhiqiza ama-gaskets, amabhande okuthutha, izivalo zeminyango yezimoto, izinto zokudonsa ukushaqeka, nezimpahla zabathengi (isb, omati berabha).
2. Amashidi e-Nitrile (NBR).
Irabha yokwenziwa eyenziwe nge-butadiene kanye ne-acrylonitrile, amashidi e-NBR ahamba phambili kuwoyela, kuphethiloli, nakumakhemikhali. Zinikeza amandla okuhle okuqina futhi zenza emazingeni okushisa asukela ku -40°C kuya ku-120°C, nakuba ukunwebeka kuphansi kune-NR.
- Izicelo: Amapayipi kawoyela negesi, amagesi enjini yezimoto, amapayipi kaphethiloli, amathangi ezimboni, nezinto zokucubungula ukudla (i-NBR yebanga lokudla).
3. I-Silicone (SI) Amashidi
Aziwa ngokumelana nezinga lokushisa okwedlulele (-60°C kuya ku-230°C, anamabanga athile afika ku-300°C), amashidi e-silicone awanabo ubuthi, aguquguqukayo, futhi amelana ne-ozone, i-UV, nokuguga. Zinamandla amaphakathi okuqinile kanye nokungazweli kahle kuwoyela.
- Izicelo: Izingxenye ze-Aerospace, ukufakwa kwe-electronics, imishini yokucubungula ukudla, okokusebenza kwezokwelapha (okungamagciwane), kanye nama-gaskets anezinga lokushisa eliphezulu.
4. Amashidi e-EPDM (Ethylene Propylene Diene Monomer).
Irabha yokwenziwa enesimo sezulu esivelele, i-UV, nokumelana ne-ozone, amashidi e-EPDM asebenza ku -40°C kuya ku-150°C futhi amelana kakhulu namanzi, isitimu, namakhemikhali athambile. Banokumelana nowoyela okuphansi kodwa ukuqina okuhle kakhulu.
- Izicelo: Ukuvikela amanzi ekwakhiweni (ophahleni, amagumbi angaphansi), ukufakwa kwangaphandle, izigxivizo zamawindi ezimoto, olayini bamachibi okubhukuda, nezinhlelo ze-HVAC.
5. Amashidi e-Neoprene (CR).
Enziwe nge-chloroprene, amashidi e-neoprene anikeza inhlanganisela elinganiselayo yokumelana nokugqokwa, ukuguquguquka, nokubambezeleka komlilo. Zenza ku -30°C kuya ku-120°C futhi zimelana ne-ozone, i-UV, namakhemikhali athambile, anokumelana nowoyela okumaphakathi.
- Izicelo: Amapayipi ezimboni, izinto zokuzivikela (amagilavu, ama-waders), izimvu zasolwandle, ama-anti-slip flooring, nokuvikelwa kwengxenye ye-elekthronikhi.
6. Amashidi Enjoloba Asetshenziswe Kabusha
Akhiqizwe kusuka kumthengi wangemuva (isb, amathayi) noma imfucumfucu yenjoloba yangemva kwemboni, lawa mashidi anobungani bemvelo, awabizi kakhulu, futhi anikeza ukumelana okuhle nokugqokwa. Ane-elasticity ephansi kanye nokubekezelela izinga lokushisa (-20°C kuya ku-80°C) kunezinto ezisabalulekile.
- Izinhlelo zokusebenza: Izindawo zokudlala, amathrekhi okusubatha, obhampa bendawo yokupaka, ukuvala umsindo, nomata benhloso evamile.
Ukuqhathanisa Ukusebenza Nokusebenza
I-Performance Metric NR NBR SI EPDM CR Recycled
Ngokusebenza, impahla ngayinye ibhekana nezidingo ezihlukile zemboni: I-NR ne-CR zibeka phambili ukuguquguquka kwezinhlelo zokusebenza eziguqukayo (isb., ukumuncwa ukushaqeka); I-NBR igxile ekuphikisweni kwamakhemikhali/kawoyela ezilungiselelweni zezimboni; I-SI ne-EPDM ihamba phambili ezindaweni eziyingozi kakhulu (izinga lokushisa eliphezulu/isimo sezulu); kanye nezindleko zebhalansi yerabha egaywe kabusha nokusimama kokusetshenziswa okungabalulekile.
Ukuqonda lo mehluko kuqinisekisa ukuthi amabhizinisi akhetha okubalulekile kweshidi lerabha ukuze athuthukise ukusebenza, anciphise izindleko zokulungisa, futhi ahlangabezane nezindinganiso zomkhakha. Njengoba ubuchwepheshe buthuthuka, abakhiqizi bayaqhubeka nokuthuthukisa izinto ezibonakalayo—njengokuthuthukisa ukumelana nowoyela we-EPDM noma ukuqinisa ukunwebeka kwenjoloba egaywe kabusha—ukunweba ukuguquguquka kwamashidi enjoloba kuzo zonke izimboni zomhlaba.
