Usayizi wokulinganisa
Usayizi wepayipi le-pvc chard id od ngaphakathi ububanzi ngaphandle ububanzi Njengoba kushiwo kokuthunyelwe kwebhulogi kwangaphambilini mayelana nobubanzi bangaphandle bepayipi le-PVC, ipayipi le-PVC kanye nokufakwa kusayizi ojwayelekile kusetshenziswa uhlelo olujwayelekile. Ngale ndlela, zonke izingxenye ezinosayizi ofanayo egameni zizohambisana. Isibonelo, zonke izihlanganisi ezingu-1″ zizolingana epayipini elingu-1″. Lokhu kubonakala kulula ngokwanele, akunjalo? Nansi ingxenye edidayo: Ububanzi bangaphandle (OD) bepayipi le-PVC bukhulu kunosayizi egameni lalo. Lokhu kusho ukuthi ipayipi le-PVC elingu-1 intshi linobubanzi bangaphandle obukhulu kune-intshi eli-1, kanti izihlanganisi ze-PVC ezingu-1 intshi zinobubanzi bangaphandle obukhulu kunepayipi.

Into ebaluleke kakhulu uma usebenza ngamapayipi e-PVC kanye nokufakwa kwawo usayizi ojwayelekile. Ukufakwa kwawo okungu-1″ kuzofakwa epayipini elingu-1″, kungaba yiShejuli 40 noma engu-80. Ngakho-ke, noma ukufakwa kwesokhethi elingu-1″ kunesikhala esibanzi kune-1″, kuzongena epayipini elingu-1″ ngoba ububanzi bangaphandle balelo payipi bukhulu kune-1″.

Ngezinye izikhathi ungase ufune ukusebenzisa izihlanganisi ze-PVC ezinamapayipi angewona awe-PVC. Kulesi simo, usayizi ojwayelekile awubalulekile njengobubanzi bangaphandle bepayipi oyisebenzisayo. Ziyahambisana uma nje ububanzi bangaphandle bepayipi bufana nobubanzi bangaphakathi (ID) befithingi elingena kuyo. Kodwa-ke, izihlanganisi ezingu-1″ namapayipi ensimbi yekhabhoni angu-1″ kungenzeka zingahambisani ngoba zinobukhulu obufanayo. Njalo yenza ucwaningo lwakho ngaphambi kokuchitha imali ezingxenyeni ezingase zingahambisani!

Chofoza lapha ukuze ufunde kabanzi mayelana nobubanzi bangaphandle be-PVC.

Izinhlobo Zokuphela kwe-PVC kanye Nezinamathiselo
Ngaphandle kwento yokunamathisela, ipayipi le-PVC kanye nezinto zokufakelwa kuzobanjwa ndawonye ngokuqinile. Kodwa-ke, ngeke kuvimbe amanzi. Uma uzodlulisa noma yiluphi uketshezi emapayipini akho, udinga ukuqinisekisa ukuthi akukho ukuvuza. Kunezindlela ezimbalwa ezahlukene zokwenza lokhu, futhi indlela oyikhethayo izoncika kulokho okuxhuma kukho.

Amapayipi e-PVCNgokuvamile azinazo iziphetho ezinentambo. Lesi ngesinye sezizathu ezenza ukuthi izifakelo eziningi ze-PVC zibe neziphetho ezishelelayo. I-“Slide” ku-PVC ayisho ukuthi uxhumano luzoshelela, kusho ukuthi ukulingana kuzoshelela ngqo epayipini. Uma ipayipi lifakwa endaweni yokushelela, uxhumano lungase lubonakale luqinile, kodwa ukuze ludlulisele noma iyiphi indlela yoketshezi, kudingeka luvalwe. I-PVC cement ivala ipayipi ngokubopha ngamakhemikhali ingxenye eyodwa yepayipi kwenye ingxenye yepulasitiki. Ukuze ugcine izifakelo ezishelelayo zivaliwe, uzodinga i-PVC primer kanye ne-PVC cement. I-Primer ithambisa ingaphakathi lokulingana ukuze ilungiselele ukunamathelisa, kuyilapho i-cement igcina izingcezu ezimbili zihlangene.

Izinto zokubopha ezinentambo zidinga ukuvalwa ngendlela ehlukile. Isizathu esiyinhloko sokuthi abantu basebenzise izingxenye ezinentambo ukuthi zingahlukaniswa uma kudingeka. Usimende we-PVC unamathelisa amapayipi ndawonye, ​​ngakho-ke uma usetshenziswa endaweni yokubopha enentambo, uzodala uphawu, kodwa izintambo ngeke zisebenze. Indlela enhle yokuvala izixhumanisi ezinentambo futhi uzigcine zisebenza ukusebenzisa itheyiphu yokubopha intambo ye-PTFE. Vele uyisonge ngentambo yesilisa izikhathi ezimbalwa futhi izogcina uxhumano luvaliwe futhi lugcotshwe. Izinto zokubopha zisengavulwa uma ufuna ukubuyela kuleyo ndawo yokubopha ukuze kulungiswe.

Ukufakwa kwefenisha okusezingeni eliphezulu kanye nokufakwa okuvamile
Amakhasimende ethu avame ukusibuza, “Uyini umehluko phakathi kokufakwa kwefenisha okusezingeni eliphezulu kanye nokufakwa okuvamile?” Impendulo ilula: ukufakwa kwefenisha okusezingeni eliphezulu akunazo iziprinti zomkhiqizi noma amabhakhodi. Kumhlophe noma kumnyama okuhlanzekile futhi akukho lutho oluprintiwe kukho. Lokhu kuzenza zilungele ukusetshenziswa lapho amapayipi ebonakala khona, kungakhathaliseki ukuthi empeleni asetshenziselwa ifenisha noma cha. Ubukhulu bufana nezesekeli ezijwayelekile. Isibonelo, kokubili ukufakwa kwefenisha okusezingeni eliphezulu okungu-1″ kanye nokufakwa okuvamile okungu-1″ kungafakwa epayipini elingu-1″.

Kubalulekile ukukhumbula ukuthi zonke izesekeli zineziphindaphindo eziningi kanye nokusetshenziswa, ngakho khumbula lokho lapho uthenga izesekeli.

I-T-shirt
A I-PVC T-shirtiyi-joint enama-terminal amathathu; amabili emgqeni oqondile kanye nelinye ohlangothini, nge-engeli engama-degree angu-90. I-Tee ivumela umugqa ukuthi uhlukaniswe ube yimigqa emibili ehlukene enoxhumano lwama-degree angu-90. Ngaphezu kwalokho, i-tee ingaxhuma izintambo ezimbili ku-wire eyodwa eyinhloko. Zivame ukusetshenziswa ekwakhiweni kwe-PVC. I-Tee iyindlela yokuhlanganisa eguquguqukayo kakhulu futhi ingenye yezingxenye ezisetshenziswa kakhulu ekufakeni amapayipi. Ama-tee amaningi aneziphetho zesokhethi ezishelelayo, kodwa kunezinhlobo zezintambo ezitholakalayo.
