Ungayikhetha njani ingca eyenziweyo? Ungayigcina njani ingca eyenziweyo?

Indlela yokukhetha ingca yokwenziwa

1. Jonga imilo yentambo yengca:

Kukho iintlobo ezininzi zesilika yengca, efana ne-U-shaped, M-shaped, diamondised, eneziqu okanye ezingenazo, njl. Okukhona ububanzi bengca bubanzi, kokukhona kusetyenziswa izinto ezininzi. Ukuba umsonto wengca wongezwa ngesiqu, oko kubonisa ukuba uhlobo oluthe tye kunye nokuqina kungcono. Kakade ke, ixabiso liphezulu. Ixabiso lolu hlobo lwengca lidla ngokuba libiza kakhulu. Ukuhamba rhoqo, okugudileyo, nokukhululekileyo kweefayibha zengca kubonisa ukuthamba okuhle kunye nokuqina kweefayibha zengca.

2. Jonga ezantsi nangasemva:

Ukuba umva wengca umnyama kwaye ujongeka ngathi yi-linoleum, sisincamathelisi se-styrene butadiene esisetyenziswa kwihlabathi liphela; Ukuba siluhlaza kwaye sijongeka ngathi sisikhumba, ngoko ke sisincamathelisi esingasemva se-SPU esikumgangatho ophezulu. Ukuba ilaphu elisisiseko kunye nesincamathelisi zibonakala zityebile, ngokubanzi kubonisa ukuba kukho izinto ezininzi ezisetyenzisiweyo, kwaye umgangatho ulungile. Ukuba zibonakala zincinci, umgangatho uphantsi. Ukuba umaleko wesincamathelisi ngasemva usasazwe ngokulinganayo ngobukhulu, ngombala ohambelanayo kwaye akukho kuvuza kombala oyintloko wesilika yengca, kubonisa umgangatho olungileyo; Ubukhulu obungalinganiyo, umahluko wombala, kunye nokuvuza kombala oyintloko wesilika yengca kubonisa umgangatho ophantsi.

3. Ukuvakalelwa kweSilika yeNgca:

Xa abantu bechukumisa ingca, kufuneka bajonge ukuba ingca ithambile okanye ayithambile, nokuba ivakala ikhululekile okanye ayikhululekile, kwaye bazive ukuba ingca ethambileyo nekhululekileyo ilungile. Kodwa eneneni, ngokuchaseneyo, ingca ethambileyo nekhululekileyo yeyona imbi kakhulu. Kufuneka kuqatshelwe ukuba xa kusetyenziswa imihla ngemihla, ingca inyathelwa ngeenyawo kwaye ayifane idibane ngqo nolusu. Yimicu yengca eqinileyo kuphela enamandla kwaye inokuqina okukhulu, kwaye ayiwi phantsi okanye iqhekeke lula ukuba inyathelwe ixesha elide. Kulula kakhulu ukwenza isilika yengca ithambe, kodwa kunzima kakhulu ukufikelela ngokuthe tye kunye nokuqina okuphezulu, oku kufuna iteknoloji ephezulu kunye neendleko eziphezulu.

4. Ukutsala iSilika yengca ukuze ubone ukumelana nokutsalwa kwayo:

Ukuxhathisa ukutsalwa kweengca yenye yezona mpawu zibalulekileyo zobugcisa beengca, ezinokulinganiswa ngokutsala imisonto yengca. Bopha iqela lemisonto yengca ngeminwe yakho uze uyitsale ngamandla. Ezo zingenakutsalwa konke konke zihlala zingcono; Ezo zitsalwa ngokungacwangciswanga, kwaye umgangatho ulungile; Ukuba imisonto yengca emininzi inokutsalwa xa amandla engekho mandla, ngokubanzi ayilunganga. Ingca enamathelayo ye-SPU akufuneki itsalwe ngokupheleleyo ngabantu abadala abane-80% yamandla, ngelixa i-styrene butadiene ngokubanzi inokukrazula kancinci, nto leyo umahluko obonakalayo phakathi kweentlobo ezimbini ze-adhesive backing.

5. Ukuvavanya ukuthamba kokucinezela intambo yengca:

Beka ingca ethe tyaba etafileni uze uyicinezele ngamandla usebenzisa isandla sakho. Ukuba ingca iyakwazi ukuphinda-phinda kwaye ibuyisele imbonakalo yayo yantlandlolo emva kokukhulula isundu, oko kubonisa ukuba ingca inokuqina okuhle, kwaye okukhona icacile kokukhona ingcono; Cinezela ingca kakhulu ngento enzima kangangeentsuku ezimbalwa okanye ngaphezulu, uze uyiphefumlele elangeni kangangeentsuku ezimbini ukuze ubone amandla engca okubuyisela imbonakalo yayo yantlandlolo.

6. Khupha umqolo:

Bamba ingca ngokuthe nkqo ngezandla zombini uze uyikrazule ngamandla umqolo njengephepha. Ukuba ayinakukrazulwa konke konke, ngokuqinisekileyo yeyona ilungileyo; Kunzima ukuyikrazula, kungcono; Kulula ukuyikrazula, ngokuqinisekileyo ayilunganga. Ngokubanzi, i-SPU adhesive ayinakukrazula ngaphantsi kwamandla angama-80% kubantu abadala; Umlinganiselo i-styrene butadiene adhesive enokukrazula ngawo ukwahluka okubonakalayo phakathi kweentlobo ezimbini ze-adhesive.

Amanqaku ekufuneka uwaqwalasele xa ukhetha utshani obungengobokwenziwa

1, Izinto zokwenza imveliso

Izinto ezisetyenziswa kwingca yokwenziwa ikakhulu yi-polyethylene (PE), i-polypropylene (PP), kunye ne-nylon (PA).

1. I-Polyethylene (PE): Ixabiso layo liphezulu, ithambile, kwaye ifana kakhulu nengca yendalo. Yamkelwe kakhulu ngabasebenzisi kwaye okwangoku yeyona nto isetyenziswa kakhulu kwimarike yifayibha yengca yokwenziwa.

2. I-Polypropylene (PP): I-fiber yengca iqinile, kwaye i-fiber elula iqhele ukusetyenziswa kwiinkundla zetenisi, kwiindawo zokudlala, kwiindlela zokubaleka, okanye kwiimhlobiso. Ukumelana kwayo nokuguguleka kubi kancinci kune-polyethylene.

3. I-Nylon: yeyona nto isetyenziswa kakhulu kwi-fiber yengca yokwenziwa kwaye yeyona nto ingcono kakhulu kwi-lawn yokwenziwa, ekwisizukulwana sokuqala se-fiber yengca yokwenziwa. I-nylon yokwenziwa itshani isetyenziswa kakhulu kumazwe aphuhlileyo afana ne-United States, kodwa e-China, ixabiso liphezulu kwaye uninzi lwabathengi alukwazi ukuyamkela.

2, Ezantsi

1. Uboya obune-sulfurized PP olukiweyo umzantsi: Luhlala ixesha elide, lusebenza kakuhle ekulweni nokugqwala, lunamathela kakuhle kwiglu nakwintambo yengca, kulula ukuliqinisa, kwaye ixabiso liphezulu ngokuphindwe kathathu kuneenxalenye ezilukiweyo zePP.

2. Isiseko esilukiweyo sePP: ukusebenza okuqhelekileyo kunye namandla okubopha abuthathaka. Isiseko seGlasi iQianwei (Isiseko seGridi): Ukusebenzisa izinto ezifana nefayibha yeglasi kunceda ekwandiseni amandla esiseko kunye namandla okubopha efayibha yengca.
