Ubhubhani we-coronavirus entsha ye-coronavirus, izixhobo zokhuseleko zonyango ezifana neeglavu zerabha zonyango zinqongophele. Nangona kunjalo, ukusetyenziswa kwerabha akukhawulelwanga kwiiglavu zerabha zonyango, irabha kunye nathi sisetyenziswa kuzo zonke iinkalo zobomi bemihla ngemihla.
1. Irabha kunye nokuthutha
Uphuhliso loshishino lwerabha alunakwahlulwa kwishishini leemoto . Ukukhula ngokukhawuleza kweshishini leemoto kwiminyaka yoo-1960 kwakhokelela ekunyukeni ngokukhawuleza kwinqanaba lemveliso yerabha. Ukuze kuhlangatyezwane neemfuno zophuhliso lweemoto, iintlobo ezahlukeneyo zamatayara zaqhubeka zivela.
Enoba lulwandle, luhamba emhlabeni okanye luhamba ngomoya, amatayara ayinxalenye ebalulekileyo yazo zonke iintlobo zothutho. Ngoko ke, kungakhathaliseki ukuba luhlobo luni lwendlela yokuthutha olungenakuhlukaniswa kwiimveliso zerabha .
2. Imigodi yerabha kunye nemizi-mveliso
Imigodi, amalahle, isinyithi kunye namanye amashishini ahlala esebenzisa iteyiphu yokuncamathelisa ukuthutha iimveliso ezigqityiweyo.
Iiteyiphu, imibhobho, amashiti erabha, iileyile zerabha kunye neemveliso zokhuselo lwabasebenzi zizo zonke iimveliso zerabha eziqhelekileyo kwicandelo loshishino.
3. Irabha kunye nezolimo, amahlathi kunye nokugcinwa kwamanzi
Ukusuka kwiitrektara kunye namatayara oomatshini abahlukeneyo bezolimo, abarhubhululi abakwizixhobo zokuvuna ezidibeneyo, izikhephe zerabha, iibhoyi zobomi, njl.
4. Irabha kunye nokhuselo lomkhosi
I-Rubber yenye yezinto ezibalulekileyo ezicwangcisiweyo, ezisetyenziswa ngokubanzi kwintsimi yezomkhosi kunye nelizwe lokukhusela, kwaye irabha inokubonwa kwizixhobo ezahlukeneyo zomkhosi.
5. Irabha kunye nokwakhiwa koluntu
Irabha isetyenziswa kwizixhobo zokwakha ezisetyenziswa kakhulu kwizakhiwo zale mihla, njengezipontshi ezifunxa isandi, iikhaphethi zerabha, nezinto ezingangenwa yimvula.
6. Irabha kunye nonxibelelwano lombane
I-Rubber inokusebenza kakuhle kwe-insulation kwaye akukho lula ukuqhuba umbane, ngoko ke iingcingo ezahlukeneyo kunye neentambo, iiglavu ezikhuselayo, njl njl. zenziwe ngerabha.
Irabha eqinileyo ikwasetyenziswa kakhulu ukwenza imibhobho yerabha, izinti zeglu, amaphepha erabha, izahluli kunye namaqokobhe ebhetri.
7. Irabha kunye nempilo yonyango
Kwisebe le-anesthesiology, isebe le-urology, isebe lotyando, isebe lotyando lwe-thoracic, isebe lamathambo, isebe le-ENT, isebe le-radiology, njl. njl. Yimveliso yerabha.
Kwiminyaka yakutshanje , irabha yesilicone iye yasetyenziswa ngokubanzi nangakumbi ekwenzeni iimveliso zonyango . Umzekelo , ukusetyenziswa kwerabha yesilicone ukwenza amalungu enziweyo kunye nezinto ezithatha indawo yezicubu zomntu zenze inkqubela enkulu. Ikhutshwe kancinci kwaye ngokuqhubekayo, ayinakuphucula kuphela isiphumo sonyango kodwa ikhuseleke ngakumbi.
8. Irabha kunye neemfuno zemihla ngemihla
Kubomi bemihla ngemihla, zininzi iimveliso zerabha ezisisebenzelayo. Ngokomzekelo, izicathulo zerabha zidla ngokugqithwa ngabahlali basezidolophini nasemaphandleni, kwaye zingenye yezona zinto zisetyenzisiweyo kwimveliso yerabha yemihla ngemihla. Ezinye ezinjengeebhatyi zemvula, iibhotile zamanzi ashushu, iibhanti ezilastiki, izinto zokudlala zabantwana, iikhushini zesiponji, neemveliso zelatex ezidipthiweyo zonke zidlala indima yazo kubomi babantu.
Iimpawu eziqhelekileyo zeemveliso zerabha zoshishino . Nangona kunjalo, zonke iimveliso zerabha zishiya ikhemikhali ebizwaantimony trisulfide. I-antimony trisulfide esulungekileyo yi-amorphous powder etyheli-bomvu, ukuxinana kwe-4.12, indawo yokunyibilika engama-550℃, ayinyibiliki emanzini kunye ne-acetic acid, inyibilika kwi-hydrochloric acid, utywala, i-ammonium sulfide kunye nesisombululo se-potassium sulfide. I-Antimony sulfide esetyenziswa kwishishini icutshungulwa kwi-stibnite ore powder. Ingumgubo omnyama okanye ongwevu-mnyama onentsimbi ecwebezelayo, enganyibiliki emanzini, kwaye inokuncipha okunamandla.
I-agent ye-vulcanizing kushishino lwerabha, i-antimony trisulfide inokusetyenziswa ngokubanzi kwi-rubber, iglasi, izixhobo zokukhuhla (i-brake pads), kunye ne-flame retardant endaweni ye-antimony oxide.
