Ndechipi chinhu chinonzi hose yekugeza yakanakisa?

- 2021-11-18-

Mukuwedzera kune musoro wakanaka wekugezera muimba yekugezera, hose yakabatanidzwa ihwowo chikamu chinokosha. Inowanzo shandiswa yekugezera hoses inogadzirwa nesimbi isina tsvina, plastiki, rabha uye zvimwe zvinhu. Mahosi emhando yakanaka ane hupenyu hurefu hwebasa uye haadi kuchinjwa kazhinji. Saka chii chinonzi material of thehose yekugeza?
1. Thehose yekugezandicho chikamu chinobatanidza shawa nepombi. Mvura inobuda mushawa inopisa kana kutonhora, saka zvinodiwa zvenyama zvakakwirira. Kazhinji, hose yacho inoumbwa nechubhu yemukati uye yekunze chubhu. Zvinhu zvemukati chubhu zviri nani EPDM rubber, uye zvinhu zvekunze chubhu zviri nani 304 Stainless simbi. Iyo hose yekugezesa yakagadzirwa nenzira iyi ichave yakakurumbira mumitambo yakasiyana-siyana, kuva nehupenyu hurefu hwebasa, uye kugeza.
Chiitiko chacho zvakare chiri nani. Imwe yacho inoshingirira kuchembera uye kupisa, uye imwe yacho iri elastic.
2. Kuramba kuchembera uye kushorwa kwekushisa kwakatanhamara. Izvi ndezvokuti kushanda kweEPDM rubber inoshandiswa mukati mehubhu iasidhi uye alkali kupikisa, kupisa kwekushisa, kunogona kumira kunyudzwa kwemvura inopisa kupfuura 100 degrees Celsius, uye haigoni kuwedzera uye deformation. Thehose yekugezainoda mvura inopisa kuti ifambe kwenguva yakareba panguva yekugeza, saka chinhu ichi ndicho chakanyatsokodzera chemukati chubhu zvinhu.
3. EPDM rubber ine elasticity iri nani. Zvinowanzodikanwa kutambanudza pombi mumvura yekugezera kuti zvive nani kushambidza. Zvinongoitika kuti zvinhu zveEPDM rubber zvine zviri nani kushanduka uye hazvizoremara nekudhonza. Zviri nyore kudzokera kumamiriro ekutanga uye yakakodzera kushandiswa kwekugeza. Ichi ndicho chimwe chezvikonzero nei EPDM rubber inoshandiswa.
4. Pakutenga ahose yekugeza, unogona kutanga kutarisa elasticity yepombi nekutambanudza. Kana yakatambanudzwa, zviri nani iyo elasticity, zviri nani kunaka kwerabha inoshandiswa. Kuti uchengetedze zvirinani rubber yemukati chubhu, kazhinji pane nylon core yakagadzirwa nepurasitiki yakavharwa acrylic.
5. Iyo 304 simbi yekunze chubhu inodzivirirawo mukati chubhu. Iyo inoumbwa nekumonera simbi isina tsvina waya, iyo inogona kudzikamisa kutambanudza kwemukati chubhu uye kudzivirira kuputika. Kuti vaderedze mari, vamwe vanogadzira vanoshandisa simbi isina tsvina pane simbi isina tsvina. Vanogona kutambanudzwa panguva yekutenga uye vozoongororwa kuti vaone kana vachizopora. Kana iri simbi isina tsvina, ichadzokera kunzvimbo yepakutanga.
