Kuvhiringika nezvese mapurasitiki akakodzera sarudzo? Kusarudza isiriyo kunogona kukonzera kunonoka kweprojekiti, kuvuza, uye kugadzirisa kunodhura. Kunzwisisa PP fittings kiyi pakusarudza chikamu chakakodzera.

PP zvigadziriso zvinobatanidza zvinogadzirwa kubva ku polypropylene, yakaoma uye inoshanda zvakasiyana-siyana thermoplastic. Iwo anonyanya kushandiswa kujoina mapaipi mumasisitimu anoda kushivirira kwakanyanya uye kuramba kwakanyanya kumakemikari, zvichiita kuti ive yakanakira maindasitiri, marabhoritari, uye kushandiswa kwemvura inopisa.

Nguva pfupi yadarika ndakafonerwa naBudi, maneja wekutenga muIndonesia. Iye inyanzvi muPVC asi aive nemutengi mutsva achikumbira "PP compression fittings"Kugadziridza marabhoritari. Budi akanga asina chokwadi zvachose pamusoro pekusiyana kwakakosha uye nguva yekukurudzira PP pamusoro pePVC yaanoziva zvakanyanya. Ainetseka nekupa mazano asiriwo. Mamiriro ake akajairika. Nyanzvi dzakawanda dzinoziva nezvemhando imwe chete kana mbiri dzepombi asi dzinowana kuti zvakasiyana-siyana zvepurasitiki zvakanyanyisa. Kuziva simba chairo rezvinhu zvakapfava semutengesi wepolypropy. pwanya izvo zvinoita kuti PP fittings ive chinhu chakakosha mumapombi emazuva ano.

Chii chinonzi PP chakakodzera?

Iwe unofanirwa kubatanidza mapaipi ebasa rinoda basa, asi hauna chokwadi kana PVC ichigona kuzvibata. Kushandisa izvo zvisiri izvo zvinozotungamira mukutadza kwehurongwa uye kudhura rework.

A PP inokwana chidimbu chekubatanidza chakagadzirwa kubva polypropylene plastiki. Mamiriro ayo ekutanga kugadzikana kwepamusoro-tembiricha (kusvika 180 ° F kana 82 ° C) uye kurwisa kwepamusoro kune acid, alkalis, uye mamwe makemikari anoparadza, ndosaka ichisarudzwa pamusoro peyakajairwa PVC munzvimbo dzakati.

Kana isu tikatarisa padhuze pane PP yakakodzera, isu tiri kunyatso kutarisa zvimiro zvepolypropylene pachayo. KusiyanaPVC, iyo inogona kuita brittle nemamwe makemikari kana kukanganisa pakupisa kwepamusoro, PP inochengetedza kuvimbika kwayo kwechimiro. Izvi zvinoita kuti ive yekuenda-kune zvinhu senge makemikari tsvina mitsetse muyunivhesiti lab kana inopisa mvura inotenderera zvishwe muchivako chekutengesa. Ndakatsanangurira Budi kuti apo zvose PVC uyePP zvigadzirwabatanidza mapaipi, mabasa avo akasiyana zvakanyanya. Iwe unoshandisa PVC kune zvakajairika mvura inotonhora pombi dzemvura. Iwe unoshandisa PP kana kupisa kana makemikari akabatanidzwa. Akabva angonzwisisa. Hazvirevi kuti ndezvipi "zviri nani," asi kuti ndezvipimudziyo wakaruramanokuda kwebasa chairo rinoda kuitwa nomutengi wake.

PP vs. PVC Fittings: A Quick Comparison

Kuita kuti sarudzo ijeke, heino kupatsanurwa kuri nyore kwekuti chinhu chimwe nechimwe chinopenya papi.

PP inorevei mukupomba?

Iwe unoona mavara "PP" mune yechigadzirwa catalog, asi anorevei chaizvo kune yako system? Kuregeredza macode emidziyo kunogona kukutungamirira kutenga chigadzirwa chisina kukodzera.

Mupombi, PP inomirira Polypropylene. Iri izita re thermoplastic polymer rinoshandiswa kugadzira pombi kana kukodzera. Ichi chinyorwa chinokuudza kuti chigadzirwa chakavakirwa kusimba, makemikari kuramba, uye kuita patembiricha yakakwira, ichisiyanisa kubva kune mamwe mapurasitiki sePVC kana PE.

Polypropylene chikamu chemhuri yezvinhu zvinonzithermoplastics. Nemashoko akareruka, izvi zvinoreva kuti unogona kuipisa kusvika pakunyungudika, woitonhodza, wobva waipisa zvakare pasina kushatisa kwakanyanya. Ichi chivakwa chinoita kuti zvive nyore kugadzira kuita maumbirwo akaomarara senge tee-fittings, magokora, uye maadapter kuburikidza nejekiseni molding. Kune maneja wekutenga saBudi, kuziva "PP" zvinoreva polypropylene ndiyo nhanho yekutanga. Chinotevera kunzwisisa kuti kune marudzi akasiyana ePP. Iwo maviri anonyanya kuzivikanwa ndiwoPP-H(Homopolymer) uye PP-R (Random Copolymer). PP-H yakanyanya kuomarara uye inowanzoshandiswa kumaindasitiri ekushandisa. PP-R inonyanya kuchinjika uye ndiyo chiyero kune ese ari maviri anopisa uye anotonhora emvura mapombi masisitimu muzvivakwa. Ruzivo urwu runomubatsira kubvunza vatengi vake mibvunzo iri nani kuti ave nechokwadi chekuti vawana chaicho chigadzirwa chavanoda.

Mhando dzePolypropylene muPiping

Chii chinonzi PP pipe?

Iwe unoda pombi yemvura inopisa kana mutsara wemakemikari uye unoda kudzivisa kuora kwesimbi. Kusarudza zvisizvo zvepombi zvinogona kukonzera kusvibiswa, kuvuza, uye hupenyu hupfupi hwesevhisi.

Pombi yePP ichubhu inogadzirwa kubva ku polypropylene plastiki, yakagadzirirwa kutakura zvinwiwa zvinopisa, mvura inonwiwa, uye makemikari akasiyana zvakachengeteka. Iyo isingaremi, haiparadzi, uye inopa yakatsetseka yemukati nzvimbo inoramba kuvakwa kwechiyero, kuve nechokwadi chekuyerera kunoenderana nenguva.

Mapaipi ePP anoshandiswa pamwe chete nePP zvishongedzo kugadzira yakakwana, homogenous system. Imwe yemabhenefiti makuru ndeyekuti vanobatanidzwa sei. Kushandisa nzira inonzikupisa fusion welding, pombi uye fitting zvinopisa uye zvakabatanidzwa pamwechete zvachose. Izvi zvinogadzira chimiro chakasimba,leak-proof jointiyo yakasimba sepombi pachayo, kubvisa zvisizvo zvisina simba zvinowanikwa mune glued (PVC) kana threaded (metal) systems. Ndakamboshanda nemutengi panzvimbo itsva yekugadzira chikafu. Vakasarudza yakazaraPP-R systemnokuda kwemvura yavo inopisa uye mitsetse yekuchenesa. Sei? Nekuti izvo zvinhu zvaisazopinza chero makemikari mumvura, uye majoini akasanganiswa aireva kuti pakanga pasina mitsetse yekuti mabhakitiriya akure. Izvi zvakavimbisa kuchena kwechigadzirwa chavo uye kuchengetedzwa kwemaitiro avo. Kwavari, mabhenefiti ePP pombi akaenda kupfuura nyore pombi dzemvura; yaiva nyaya ye quality control.

Chii chinonzi PB fittings?

Iwe unonzwa nezvePB fittings uye unoshamisika kana iri imwe nzira yePP. Kuvhiringidza zvinhu zviviri izvi kunogona kuva kukanganisa kukuru, sezvo munhu ane nhoroondo yekukundikana kwakapararira.

PB fittings zvibatanidza zvePolybutylene (PB) pombi, inochinjika pombi zvinhu yaimbozivikanwa pakugara pombi dzemvura. Nekuda kwekutadza kwakanyanya kubva mukuparara kwekemikari, PB pombi uye zvigadziriso zvayo hazvichatenderwe nemakodhi mazhinji epombi uye zvinoonekwa sezvisina basa uye zvisingavimbike.

Ichi chinhu chakakosha chedzidzo kune chero munhu ari muindasitiri. Nepo PP (Polypropylene) iri yazvino, yakavimbika zvinhu, PB (Polybutylene) ndiro dambudziko rayo rakatangira. Kubva kuma1970 kusvika kuma1990, PB yaive yakaiswa zvakanyanya kumitsetse yemvura inopisa uye inotonhora. Nekudaro, zvakaonekwa kuti makemikari akajairika mumvura yemunisiparati, senge chlorine, akarwisa polybutylene nemidziyo yayo yepurasitiki, ichiita kuti ive brittle. Izvi zvakakonzera kutsemuka kwakamwe kamwe uye kudonha kwenjodzi, zvichikonzera mabhiriyoni emadhora mukukuvadzwa kwemvura mudzimba dzisingaverengeki. Kana Budi ikawana chikumbiro chenguva nenguva chePB fittings, kazhinji ndeyekugadzirisa. Ndakamudzidzisa kuti akurumidze kuraira mutengi nezve njodzi yePB system yese uye ndinokurudzira kutsiva kwakazara nezvinhu zvakagadzikana, zvemazuva ano senge.PP-R or PEX. Hazvisi zvekutengesa zvakakura; ndezvekudzivirira mutengi kubva mukukundikana mune ramangwana.

Polypropylene (PP) vs. Polybutylene (PB)

Mhedziso

PP fittings, yakagadzirwa kubva yakasimba polypropylene, ndiyo yekuenda-kusarudzo yemvura inopisa uye makemikari masisitimu. Iwo azvino, akavimbika mhinduro, kusiyana neakare, akakundikana zvinhu senge polybutylene.
