Matanho akakosha ekugadzira pasi pePVC
Pfupiso Nhanganyaya:
Uriri hwePVC hunoshandiswa zvakanyanya muzvipatara, makireshi, matare ebhedhi nedzimwe nzvimbo. Semhando itsva yezvinhu zvekugadzira pasi, ndedzipi nyaya dzatinofanira kutarisisa patinenge tichigadzira pasi?
Kuvaka kwekuzvienzanisa:
1. Danho rekutanga ndere kuchenesa pasi rinoda kuzvienzanisa woisa chinhu chinogadzirisa. Mushure mekushandisa chinhu chinogadzirisa kamwe chete, unofanira kumirira kusvika chaoma usati waisa kechipiri. Ingoisa kaviri zvachose. Kana chaoma zvachose kaviri, tanga kurova. Kurova kunofanira kutora nguva yakareba kuti chinhu chacho chivhurwe zvachose.
2. Kukwesha nekukwesha. Kana yakaitwa pasi, inowanzova neukobvu hwema 3 mm. Kana ivhu risina kuenzana, inogona kugadzirwa neukobvu hwema 5-6 mm.
3. Kurapa kubvisa matumbu kunonyanya kukonzera kubvisa matumbu patsvina. Zvakanaka kuapeta katatu kusvika kashanu uchishandisa chishandiso.
4.Kuti uchengetedze chigadzirwa chapera, zvinotora maawa angangoita makumi maviri nemana mushure mekunge chivakwa chapera vanhu vasati vapinda, uye chichawedzerwa kusvika maawa makumi mana nemasere pamazuva ekunaya kwemvura. Kana hwaro hwepasi hwakanaka, unogona kufuratira danho rekuzvienzanisa.
Kuisa pasi:
1. Ingava roll kana sheet, inofanira kusiiwa panzvimbo yacho kwemaawa anopfuura makumi maviri nemana kuti idzorere ndangariro yechinhu chacho uye kuti tembiricha irambe ichiwirirana nenzvimbo yekuvaka. Shandisa muchina wekucheka nekuchenesa maburi eroll.
2. Pakuisa zvinhu, kupindirana pakati pezvidimbu zviviri zvechinhu kunofanira kuchekwa nekupindirana. Kazhinji, kupindirana kunofanirwa kunge kuri 3 cm. Chenjerera kuti urambe uchicheka nebanga rimwe chete. Pakuisa zvinhu, peta mugumo mumwe weroro. Chenesa pasi nekumashure kweganda kutanga, wobva wakwesha guruu pasi.
3. Mushure mekunge pasi panamatwa, shandisa chivharo chekork kusundira pasi kuti pasi rive rakati sandara wobva wadzvanya mweya. Wobva washandisa simbi ine simba re50 kana 75 kg yekumonera pasi zvakaenzana uye nekukurumidza kugadzirisa kumonereka kwemajoini ekubatanidza. Guruu rakawandisa riri pamusoro pepasi rinofanira kubviswa nenguva.
Kushongedza waya:
1. Kurovera kunofanira kuitwa mushure mekunge guruu ranyatsosimba. Shandisa chishandiso chakakosha chekurovera kuti urovere pamwe chete nemajoini. Kuti usimbise welding, mipata haifanirwe kupfuura nepasi. Zvinokurudzirwa kuti kudzika kwegrooving kuve 2/3 yeukobvu hwepasi. Kumagumo uko muvhiyi wemusono usingakwanise kucheka, shandisa muvhiyi wemusono wemaoko kuvhura mipata ine kudzika nehupamhi hwakafanana.
2.Usati wabatanidza, guruva nemarara zvakasara mumugero zvinofanirwa kubviswa.
3. Tembiricha yepfuti yekuwelding inofanira kuiswa pa350°C. Pakumhanya kwakakodzera kwekuwelding (kuti uve nechokwadi chekuti tsvimbo yekuwelding inonyunguduka), dzvanya tsvimbo yekuwelding mugomba rakavhurika nekumhanya kwakafanana.
4. Kana tsvimbo yekuwelda yatonhodzwa zvishoma, shandisa muchina wekuwelda kana muchina wekucheka wakaita semwedzi kuti ucheke chikamu chetsvimbo yekuwelda chakakwirira kupfuura pasi. Kana tsvimbo yekuwelda yatonhodzwa zvakakwana, shandisa muchina wekuwelda kana muchina wekucheka wakaita semwedzi kuti ucheke chikamu chasara chetsvimbo yekuwelda.
