Amashiti erabha ayimfuneko kuwo wonke amashishini, kwaye usetyenziso lwawo luchazwa ngokwezinto ezisisiseko. Ukusuka kwirabha yendalo ukuya kwi-synthetics ephezulu kunye nokwahluka okuhlaziyiweyo, uhlobo ngalunye lubonelela ngeempawu zokusebenza ezizodwa ezilungiselelwe iimeko ezithile zokusetyenziswa, ukwenza ukhetho lwemathiriyeli lubaluleke kakhulu ekusebenzeni ngokufanelekileyo kunye nokuqina. Apha ngezantsi kukho ucazululo oluneenkcukacha lwemathiriyeli yerabha eqhelekileyo, iipropathi zazo, usetyenziso, kunye nothelekiso olungundoqo lomsebenzi.
IiMathiriyeli zePhepha leRabha eliPhambili: Iipropati kunye nezicelo
1. Amaphepha eRabha yeNdalo (NR).
Ithatyathwe kwi-latex yemithi yerabha, amashiti e-NR axabiswa ngenxa yokunwebeka okukhethekileyo (ubude ukuya kuma-800%), ukomelela okuphezulu, kunye nokomelela okuphezulu. Ziqhuba kakuhle kumaqondo obushushu aphakathi (-50°C ukuya kuma-80°C) kodwa zisesichengeni kwioli, kwi-ozone nakwimitha yeUV.
- Usetyenziso: Igaskithi yokwenziwa ngokubanzi, amabhanti okuhambisa, amacango atywiniweyo eemoto, izinto zokuthambisa ezothusayo, kunye nempahla yabathengi (umz., iimethi zerabha).
2. I-Nitrile (NBR) Amaxwebhu
Irabha eyenziwe nge-butadiene kunye ne-acrylonitrile, i-NBR sheets igqwesileyo kwi-oyile, i-fuel, kunye ne-chemical resistance. Banikezela ngamandla okuqina kwaye basebenze kumaqondo obushushu ukusuka kwi -40 ° C ukuya kwi-120 ° C, nangona ukuqina kuphantsi kune-NR.
- Izicelo: Imibhobho ye-oyile nerhasi, iigaskets ze-injini yemoto, imibhobho yamafutha, iitanki zemizi-mveliso, kunye nezixhobo zokulungisa ukutya (i-NBR yebakala lokutya).
3. I-Silicone (SI) Amaxwebhu
Eyaziwayo ngokumelana nokushisa okugqithisileyo (-60 ° C ukuya kwi-230 ° C, kunye namabanga athile ukuya kwi-300 ° C), amaphepha e-silicone awanatyhefu, aguquguqukayo, kwaye axhatshazwa kwi-ozone, i-UV, kunye nokuguga. Banamandla aphakathi kunye nokunganyangeki kweoli.
- Usetyenziso: Izixhobo ze-aerospace, ukugqunywa kwe-electronics, oomatshini bokwenza ukutya, izixhobo zonyango (ezingenantsholongwane), kunye neegesi ezinobushushu obuphezulu.
4. I-EPDM (Ethylene Propylene Diene Monomer) Amaxwebhu
Irabha eyenziweyo enemozulu ebalaseleyo, i-UV, kunye nokumelana ne-ozone, amaphepha e-EPDM asebenza kwi--40 ° C ukuya kwi-150 ° C kwaye axhathisa kakhulu kumanzi, umphunga, kunye neekhemikhali ezithambileyo. Banokumelana ne-oyile ephantsi kodwa ukuqina okugqwesileyo.
- Usetyenziso: Ulwakhiwo lokuthintela amanzi (uphahla, amagumbi angaphantsi), ukugqunywa kwangaphandle, itywina lefestile yeemoto, iilitha zamadama okuqubha, kunye neenkqubo zeHVAC.
5. I-Neoprene (CR) Amaxwebhu
Eyenziwe kwi-chloroprene, amaphepha e-neoprene anika umxube olungeleleneyo wokumelana nokunxiba, ukuguquguquka, kunye nokuncitshiswa komlilo. Zenza kwi--30 ° C ukuya kwi-120 ° C kwaye zixhathisa i-ozone, i-UV, kunye neekhemikhali ezithambileyo, kunye nokumelana neoli ephakathi.
- Izicelo: I-industrial hoses, izixhobo zokukhusela (iiglavu, ii-waders), izitywina zaselwandle, i-anti-slip flooring, kunye nokukhusela icandelo lombane.
6. Iishiti zeerabha ezisetyenzisiweyo
Eveliswe kumthengi wasemva (umzekelo, amatayara) okanye inkunkuma yerabha yasemva kwamashishini, la maphepha alungele ukuphilisana kwendalo, angabizi kakhulu, kwaye anika ukuxhathisa okuhle kokunxiba. Zine-elasticity ephantsi kunye nokunyamezela ukushisa (-20 ° C ukuya ku-80 ° C) kunezixhobo ezinyulu.
- Usetyenziso: Imiphezulu yebala lokudlala, iingoma zembaleki, iibhampa kwindawo yokupaka, ukugqunywa kwesandi, kunye neemethi zenjongo jikelele.
Intsebenzo kunye nothelekiso lweMsebenzi
Performance Metric NR NBR SI EPDM CR Recycled
Ngokusebenzayo, imathiriyeli nganye ijongana neemfuno ezahlukeneyo zeshishini: i-NR kunye ne-CR zibeka phambili ukuguquguquka kwezicelo eziguqukayo (umzekelo, ukufunxa ukothuka); I-NBR igxile ekuxhathiseni imichiza/i-oyile kwizicwangciso zemizi-mveliso; I-SI kunye ne-EPDM zigqwesa kwiindawo ezigqithisileyo (iqondo lokushisa eliphezulu / imozulu); kunye neendleko zerabha ezilungelelanisiweyo kunye nozinzo kusetyenziso olungabalulekanga.
Ukuqonda lo mahluko kuqinisekisa ukuba amashishini akhetha imathiriyeli yerabha echanekileyo ukuze kuphuculwe ukusebenza kakuhle, ukunciphisa iindleko zokugcinwa, kunye nokuhlangabezana nemigangatho yoshishino. Njengoko ubuchwephesha buhambela phambili, abavelisi bayaqhubeka nokuphucula iipropathi zemathiriyeli-ezifana nokuphucula ukuxhathisa kwe-oyile ye-EPDM okanye ukomeleza ukuqina kwerabha esetyenzisiweyo-ukwandisa ukuguquguquka kwamaphepha erabha kuwo wonke amashishini ehlabathi.
