Isu tinodonongodza mapoinzi akakosha pakati pezvinhu zviviri (simbi yakapfava kana simbi isina tsvina) pazasi. Simbi isina tsvina inosimba zvakanyanya mumamiriro emunyu uye inogona kushandiswa muindasitiri yezvekudya, nepo simbi yakapfava yakasimba uye inogona kuisa zvakanyanya kudzvanywa pane honye drive.

simbi yakapfava:
Simbi yakapfava, inozivikanwawo sekabhoni simbi, ndiyo yakajairika nzira yesimbi mune zvese zvinoshandiswa, uye hose clamps hazvisi izvo. Iyo zvakare imwe yemagiredhi akafararira esimbi anovhara huwandu hwakasiyana hwema mechanical properties. Izvi zvinoreva kuti kunzwisisa uye kutsanangura giredhi rakakodzera kunogona kuve nekukanganisa kukuru pakuita kwechigadzirwa chakapedzwa. Semuyenzaniso, kushushikana uye zvinodiwa zvemashizha esimbi anoumba mota dzemuviri mapaneru akasiyana chaizvo neaya ehose entrainment materials. Muchokwadi, iyo yakanakira hose clamp yezvinhu zvakatemwa haina kutombofanana negoko uye tambo.

Imwe yakashata yesimbi yakapfava ndeyokuti ine yakaderera kwazvo yepanyama corrosion resistance. Izvi zvinogona kukundwa nekuisa coating, kazhinji zinc. Misiyano yenzira dzekupfekedza uye zviyero zvinoreva kuti corrosion resistance inogona kuva imwe nzvimbo iyo hose clamps inosiyana zvakanyanya. Iyo British Standard yehose clamps inoda maawa makumi mana nemasere ekuramba kuoneka tsvuku ngura mune 5% isina kwayakarerekera munyu yekupfapfaidza bvunzo, uye zvakawanda zvisina kunyorwa zvigadzirwa zvekite zvinotadza kuita izvi zvinodiwa.

Simbi isina ngura:
Simbi isina tsvina yakanyanya kuoma kupfuura simbi yakapfava munzira dzakawanda, kunyanya kana zvasvika kune hose clamps, sezvo vagadziri vanotyaira mari vanowanzo shandisa musanganiswa wemagiredhi akasiyana-siyana kuti vape chigadzirwa chine mutengo wakaderera wekugadzira uye kuderedzwa kwekuita.

Vazhinji vanogadzira hose clamp vanoshandisa ferritic Stainless simbi seimwe nzira kune simbi yakapfava kana seyakachipa isingadhuri kune austenitic Stainless simbi. Nekuda kwekuvapo kwechromium mune alloy, ferritic simbi (inoshandiswa muW2 uye W3 mamakisi, mune 400-giredhi akatevedzana) haidi chero humwe hugadziriso hwekuvandudza corrosion resistance. Zvisinei, kusavapo kana kuderera kwe nickel yesimbi iyi zvinoreva kuti maitiro ayo ari munzira dzakawanda dzakaderera kune austenitic stainless steels.

Austenitic Stainless steels ine nhanho yepamusoro-soro yekurarisa kune ese marudzi ekuora, kusanganisira maasidhi, ane yakakura kwazvo yekushanda tembiricha renji, uye asiri magineti. Kazhinji 304 uye 316 mamakisi ezvimedu zvesimbi isina tsvina anowanikwa; zvese zviri zviviri zvinotenderwa kushandiswa kwemugungwa uye Lloyd's Rejista mvumo, nepo ferritic mamakisi haagone. Aya magiredhi anogona zvakare kushandiswa muindasitiri yezvekudya uye zvinwiwa, uko maasidhi akadai seacetic, citric, malic, lactic uye tartaric acids anogona kusabvumidza kushandiswa kwesimbi ferritic.
