Umaleko Wokukhusela: Usebenzisa ukuluka kobhedu olufakwe kwiitini okanye ukhuselo lweteyiphu yobhedu olufakwe kwiitini ukuthintela ngempumelelo ukuphazamiseka kwe-electromagnetic kunye nokuphucula amandla okulwa nokuphazamiseka.
Umaleko weSheath: Ngokwesiqhelo wenziwe nge-fluoroplastics (umz., i-PFA, i-FEP) okanye irabha ye-silicone, enika ukumelana okuhle kakhulu nobushushu obuphezulu, ukumelana nokugqwala, kunye nokumelana neoyile.
Umaleko Wesikrweqe: Kwiimodeli ezithile, iteyiphu yentsimbi okanye isikrweqe sentsimbi yentsimbi sinokusetyenziswa ukuphucula amandla oomatshini kunye nokusebenza kokutsalwa.

3. Iimpawu:

Ukumelana nobushushu obuphezulu: Ububanzi bobushushu bokusebenza, ukuya kuthi ga kwi-260°C, kwanakwi-285°C kwezinye iimodeli.
Ukumelana Nokugqwala: Iyakwazi ukumelana nee-asidi, ii-alkali, iioyile, amanzi, kunye neegesi ezahlukeneyo ezigqwalisayo.
Ukuthintela ilangatye: Iyahambelana nomgangatho we-GB12666-90, iqinisekisa umonakalo omncinci xa kutsha.
Amandla okulwa nokuphazamiseka: Uyilo lokukhusela lunciphisa ngempumelelo ukuphazamiseka kwe-electromagnetic, luqinisekisa ukuhanjiswa kwesignali okuzinzileyo.

Ukusebenza Okuthile kunye neeNzuzo zokuxhathisa amaqondo obushushu aphezulu kwiintambo ezikhuselweyo zokuchasana nokugqwala kumaqondo obushushu aphezulu

1. Ukumelana nobushushu obuphezulu:

Iintambo ezikhuselweyo ezichasene nokugqwala ezimelana nobushushu obuphezulu zenziwe ngezinto ezikhethekileyo ezigcina ukusebenza okuzinzileyo kwiindawo ezinobushushu obuphezulu kakhulu. Umzekelo, ezinye iintambo zinokusebenza kumaqondo obushushu afikelela kwi-200°C nangaphezulu, nto leyo eyenza ukuba zifaneleke kwiindawo zoshishino ezinobushushu obuphezulu ezifana nepetroleum, iikhemikhali, i-metallurgy, kunye namandla. Ezi ntambo ziphathwa ngendlela ekhethekileyo, zibonelela ngozinzo oluhle kakhulu lobushushu kunye nokumelana nokwaluphala okanye ukuguquka.

2. Ukumelana nokugqwala:

Iintambo ezikhuselweyo ezichasene nokugqwala ezinokumelana nobushushu obuphezulu zisebenzisa izinto ezichasene nokugqwala ezifana ne-fluoroplastics kunye nerabha ye-silicone, zimelana ngempumelelo neegesi ezigqwala okanye ulwelo kwiindawo ezinobushushu obuphezulu kwaye zandisa ubomi benkonzo. Umzekelo, ezinye iintambo zigcina ukusebenza kwiindawo eziqala kwi -40°C ukuya kwi-260°C.

3. Ukusebenza koMbane okuZinzileyo:

Iintambo ezikhuselweyo ezichasene nokugqwala ezinokumelana nobushushu obuphezulu zibonisa iimpawu ezintle zokukhusela umbane, zinokumelana nombane ophezulu, zinciphise ilahleko ze-frequency ephezulu, kwaye ziqinisekise ukudluliselwa kwesignali okuthembekileyo. Ukongeza, uyilo lwazo lokukhusela lunciphisa ngempumelelo ukuphazamiseka kwe-electromagnetic (EMI) kunye nokuphazamiseka kwe-radio frequency (RFI), ukuqinisekisa ukudluliselwa kwesignali okuzinzileyo nokukhuselekileyo.

4. Ukusebenza kokuLibazisa ilangabi kunye noKhuseleko:

Iintambo ezikhuselweyo ezichasene nokugqwala ezimelana nobushushu obuphezulu zihlala zisebenzisa izinto ezithintela ukutsha nokuba kushushu kakhulu okanye kwiimeko zomlilo, ngaloo ndlela zinciphisa umngcipheko womlilo. Umzekelo, ezinye iintambo ziyahambelana nomgangatho we-GB 12660-90, zibonelela ngokumelana nokutsha okuphezulu.

5. Amandla oomatshini kunye nokumelana nokwaluphala:

Iintambo ezikhuselweyo ezimelana nokugqwala ezishushu kakhulu zinamandla aphezulu oomatshini, nto leyo ebenza bakwazi ukumelana nokuxinana, ukugoba kunye noxinzelelo oluxinzelelweyo. Kwangaxeshanye, izinto zazo zangaphandle zeshelufu zinokumelana nokuguga okugqwesileyo, okuvumela ukusetyenziswa ixesha elide kwiindawo ezinzima.

6.Ukusebenza Okubanzi:

Iintambo ezikhuselweyo ezimelana nokugqwala ezinobushushu obuphezulu zifanelekile kwiindawo ezahlukeneyo ezinobushushu obuphezulu nezingcolisayo, njengezakhiwo eziphakamileyo, amasimi eoyile, izikhululo zamandla, imigodi, kunye nezikhululo zeekhemikhali. Uyilo lwazo kunye nokukhethwa kwezinto ziyahlangabezana neemfuno ezikhethekileyo zamacandelo ahlukeneyo emizi-mveliso.
