Tsis meej pem los ntawm tag nrho cov kev xaiv yas haum? Xaiv qhov tsis ncaj ncees lawm tuaj yeem ua rau qhov project qeeb, xau, thiab kev kho nqi kim. Nkag siab txog PP fittings yog qhov tseem ceeb rau kev xaiv qhov zoo.

PP fittings yog cov khoom sib txuas ua los ntawm polypropylene, tawv thiab ntau yam thermoplastic. Lawv feem ntau yog siv los koom nrog cov kav dej hauv cov tshuab uas yuav tsum tau ua kom sov siab thiab ua haujlwm zoo rau cov tshuaj, ua rau lawv zoo tagnrho rau kev lag luam, chav kuaj, thiab kev siv dej kub.

Tsis ntev los no kuv tau hu xov tooj nrog Budi, tus thawj tswj kev yuav khoom hauv Indonesia. Nws yog tus kws tshaj lij hauv PVC tab sis muaj ib tus neeg siv khoom tshiab nug "PP compression fittingsBudi tsis paub meej txog qhov sib txawv ntawm qhov tseem ceeb thiab thaum twg yuav pom zoo PP hla PVC nws paub zoo. Nws tau txhawj xeeb txog kev muab cov lus qhia tsis raug. Nws qhov xwm txheej yog qhov tshwm sim ntau. fittings ib qho tseem ceeb ntawm cov kav dej niaj hnub.

PP yog dab tsi?

Koj yuav tsum tau txuas cov kav dej rau txoj haujlwm xav tau, tab sis koj tsis paub tseeb tias PVC tuaj yeem ua tau. Kev siv cov khoom siv tsis raug yuav ua rau lub cev tsis ua haujlwm thiab ua haujlwm kim dua.

PP haum yog ib qho kev sib txuas ua los ntawm cov yas polypropylene. Nws cov yam ntxwv tseem ceeb yog qhov kub siab ruaj khov (txog 180 ° F lossis 82 ° C) thiab ua haujlwm zoo rau cov kua qaub, alkalis, thiab lwm yam tshuaj corrosive, uas yog vim li cas nws tau xaiv dhau tus qauv PVC hauv ib puag ncig tshwj xeeb.

Thaum peb saib ze dua ntawm PP haum, peb tab tom saib tiag tiag ntawm cov khoom ntawm polypropylene nws tus kheej. Tsis zoo liPVC, uas tuaj yeem ua nkig nrog qee yam tshuaj lossis deform ntawm qhov kub siab dua, PP tswj nws cov qauv kev ntseeg siab. Qhov no ua rau nws mus rau cov khoom siv rau cov khoom xws li cov kab khib nyiab hauv tsev kawm ntawv qib siab lossis cov dej kub ncig hauv lub tsev lag luam. Kuv piav qhia rau Budi tias thaum ob leeg PVC thiabPP cov khoom sivtxuas cov kav dej, lawv txoj haujlwm sib txawv heev. Koj siv PVC rau cov kav dej txias. Koj siv PP thaum tshav kub lossis tshuaj lom neeg. Nws tam sim ntawd to taub. Nws tsis yog hais txog qhov twg yog "zoo dua," tab sis qhov twg yogcuab tamrau txoj haujlwm tshwj xeeb uas nws cov neeg siv khoom xav tau ua.

PP vs. PVC Fittings: Kev sib piv ceev

Txhawm rau ua qhov kev xaiv kom pom tseeb, ntawm no yog qhov yooj yim tawg ntawm qhov twg txhua yam khoom ci.

PP txhais li cas hauv cov kav dej?

Koj pom cov ntawv "PP" hauv cov khoom lag luam catalog, tab sis lawv txhais li cas rau koj lub cev? Kev tsis quav ntsej cov cai ntawm cov khoom siv tuaj yeem ua rau koj mus yuav ib yam khoom uas tsis tsim nyog.

Hauv piping, PP stands rau Polypropylene. Nws yog lub npe ntawm cov thermoplastic polymer siv los ua cov yeeb nkab lossis haum. Daim ntawv qhia no qhia koj tias cov khoom tsim los rau kev ua haujlwm ntev, tshuaj tiv thaiv, thiab kev ua haujlwm ntawm qhov kub siab, qhov txawv ntawm lwm cov yas xws li PVC lossis PE.

Polypropylene yog ib feem ntawm tsev neeg cov khoom hu uathermoplastics. Hauv cov ntsiab lus yooj yim, qhov no txhais tau tias koj tuaj yeem ua kom sov nws mus rau qhov chaw melting, txias nws, thiab rov ua dua nws dua yam tsis muaj kev puas tsuaj loj. Cov cuab yeej no ua rau nws yooj yim los tsim rau hauv cov duab zoo li tee-fittings, lub luj tshib, thiab cov khoom siv los ntawm kev txhaj tshuaj molding. Rau tus thawj tswj kev yuav khoom zoo li Budi, paub "PP" txhais tau tias polypropylene yog thawj kauj ruam. Tom ntej no yog nkag siab tias muaj ntau hom PP. Qhov thib ob feem ntau yogPP-H(Homopolymer) thiab PP-R (Random Copolymer). PP-H yog nruj dua thiab feem ntau siv rau kev lag luam. PP-R hloov tau yooj yim dua thiab yog tus qauv rau cov kav dej kub thiab dej txias hauv cov tsev. Qhov kev paub no pab nws nug nws cov neeg siv khoom cov lus nug zoo dua kom ntseeg tau tias lawv tau txais cov khoom raws nraim lawv xav tau.

Hom Polypropylene hauv Piping

PP yeeb nkab yog dab tsi?

Koj xav tau ib lub yeeb nkab rau cov dej kub los yog cov kab tshuaj lom neeg thiab xav kom tsis txhob muaj qhov corrosion ntawm hlau. Kev xaiv cov khoom siv yeeb nkab tsis raug tuaj yeem ua rau muaj kev sib kis, xau, thiab ua haujlwm luv luv.

PP yeeb nkab yog ib lub raj tsim los ntawm polypropylene yas, tsim tshwj xeeb los thauj cov kua kub, dej haus, thiab ntau yam tshuaj lom neeg. Nws yog ib lub teeb yuag, tsis corrode, thiab muab ib tug du sab hauv nto uas resists scale buildup, xyuas kom meej txaus txaus nyob rau hauv lub sij hawm.

PP kav yog siv ua ke nrog PP fittings los ua kom tiav, homogenous system. Ib qho zoo tshaj plaws yog qhov lawv koom nrog. Siv ib txoj kev hu uaThaum tshav kub kub fusion vuam, cov yeeb nkab thiab fittings yog rhuab thiab fused ua ke mus tas li. Qhov no tsim ib qho khoom,leak-proof sib koom ua keuas muaj zog npaum li cov yeeb nkab nws tus kheej, tshem tawm cov ntsiab lus tsis muaj zog pom nyob rau hauv glued (PVC) los yog threaded (hlau) tshuab. Ib zaug kuv tau ua haujlwm nrog tus neeg siv khoom ntawm qhov chaw ua zaub mov tshiab. Lawv xaiv tag nrhoPP-R qhov systemrau lawv cov dej kub thiab tu kab. Vim li cas? Vim tias cov khoom yuav tsis tso cov tshuaj rau hauv dej, thiab cov pob qij txha fused txhais tau tias tsis muaj cov kab mob loj hlob. Qhov no tau lees paub qhov purity ntawm lawv cov khoom thiab kev nyab xeeb ntawm lawv cov txheej txheem. Rau lawv, cov txiaj ntsig ntawm PP yeeb nkab tau dhau los ntawm cov kav dej yooj yim; nws yog ib qho teeb meem ntawm kev tswj kom zoo.

PB fittings yog dab tsi?

Koj hnov ​​​​txog PB fittings thiab xav paub seb lawv puas yog lwm txoj hauv kev rau PP. Tsis meej pem ob cov ntaub ntawv no tuaj yeem yog qhov yuam kev loj, vim tias ib tus muaj keeb kwm ntawm kev ua tsis tiav.

PB fittings yog cov khoom sib txuas rau cov kav dej Polybutylene (PB), cov kav dej hloov tau yooj yim ib zaug rau cov kav dej hauv tsev. Vim tias qhov ua tsis tau zoo los ntawm cov tshuaj lom neeg tawg, PB piping thiab nws cov fittings tsis tau pom zoo los ntawm cov kav dej feem ntau thiab suav tias yog siv tsis tau thiab tsis ntseeg.

Qhov no yog lub ntsiab lus tseem ceeb ntawm kev kawm rau txhua tus hauv kev lag luam. Thaum PP (Polypropylene) yog cov khoom siv niaj hnub, txhim khu kev qha, PB (Polybutylene) yog nws cov teeb meem ua ntej. Txij xyoo 1970 mus txog xyoo 1990, PB tau dav ntsia rau cov kab dej kub thiab dej txias. Txawm li cas los xij, nws tau pom tias cov tshuaj lom neeg hauv cov dej hauv nroog, xws li chlorine, tawm tsam cov polybutylene thiab nws cov khoom siv yas, ua rau lawv nkig. Qhov no ua rau muaj kev tawg sai sai thiab muaj kev puas tsuaj loj heev, ua rau ntau lab nyiaj daus las hauv dej puas tsuaj thoob plaws ntau lub tsev. Thaum Budi tau txais qee qhov kev thov rau PB fittings, nws feem ntau yog kho. Kuv tau cob qhia nws tam sim ntawd qhia cov neeg siv khoom txog kev pheej hmoo ntawm tag nrho PB system thiab pom zoo kom hloov tag nrho nrog cov khoom ruaj khov, niaj hnub zoo liPP-R or PEX. Nws tsis yog hais txog kev muag khoom loj dua; nws yog hais txog kev tiv thaiv tus neeg siv khoom los ntawm kev ua tsis tiav yav tom ntej.

Polypropylene (PP) vs Polybutylene (PB)

Xaus

PP fittings, ua los ntawm cov polypropylene ruaj khov, yog qhov kev xaiv rau cov dej kub thiab tshuaj lom neeg. Lawv yog cov khoom siv niaj hnub, txhim khu kev qha, tsis zoo li cov laus, cov ntaub ntawv ua tsis tiav zoo li polybutylene.
