Kulumikizana ndi opanga osiyanasiyana ndikofunikira kuti mupeze chitsogozo pakugwiritsa ntchito moyenera komanso masitayelo omwe akupezeka kuti ajowine monga tafotokozera m'chikalatachi motere.
Njira Zolumikizirana
Pali mitundu ingapo yamagulu osakanikirana a kutentha omwe amagwiritsidwa ntchito pakali pano: Butt, Saddle, ndi Socket Fusion.Additionally, electrofusion (EF) jointing imapezeka ndi EF couplers yapadera ndi zomangira zitsulo.
Mfundo ya kusakaniza kutentha ndi kutenthetsa malo awiri kuti atenthedwe, kenaka kuwaphatikiza pamodzi pogwiritsa ntchito mphamvu yokwanira. Mphamvuyi imapangitsa kuti zinthu zosungunuka ziziyenda ndikusakanikirana, zomwe zimapangitsa kuti ziphatikizidwe. Ikaphatikizidwa molingana ndi chitoliro ndi/kapena njira za opanga, malo olumikizirana mafupawo amakhala amphamvu ngati kapena amphamvu kuposa, chitoliro chomwe chimakhala ndi mphamvu zolimba komanso zophatikizika komanso zolumikizana bwino ndi umboni wotsikirapo. Mgwirizanowo ukangozizira mpaka pafupi ndi kutentha kozungulira, umakhala wokonzeka kugwiridwa.Magawo otsatirawa a mutu uno amapereka malangizo okhudza njira iliyonse yolumikizira iyi.
Kuphatikizika kwa matako Masitepe
1. Mapaipi ayenera kuikidwa mu makina owotcherera, ndipo mapeto ake atsukidwe ndi osayikamo mowa kuti achotse zinyalala, fumbi, chinyezi, ndi mafilimu amafuta ku zone pafupifupi 70 mm kuchokera kumapeto kwa chitoliro chilichonse, mkati ndi kunja kwake.
2.Mapeto a mapaipi amakonzedwa pogwiritsa ntchito chodulira chozungulira kuchotsa malekezero onse ovuta ndi zigawo za okosijeni. Nkhope zomalizidwa ziyenera kukhala zazikulu komanso zofanana.
3. Mapeto a mapaipi a PE amatenthedwa ndi kugwirizana pansi pa kupanikizika (P1) motsutsana ndi mbale yamoto. Zipinda zotenthetsera ziyenera kukhala zoyera komanso zopanda kuipitsidwa, komanso kusungidwa mkati mwa kutentha kwapamwamba (210±5 ℃C kwa PE80, 225±5 C kwa PE100). Kulumikizana kumasungidwa mpaka ngakhale kutentha kumakhazikitsidwa mozungulira chitoliro chimatha, ndipo kuthamanga kwa kugwirizana kumachepetsedwa mpaka mtengo wotsika P2 (P2 = Pd) .Kulumikizana kumasungidwa mpaka "Kutentha-Kutentha Kwambiri" kutha.
Buttfusion
Kuphatikizika kwa matako ndi njira yomwe imagwiritsidwa ntchito kwambiri polumikiza utali wa mapaipi a PE ndi mapaipi ku zida za PE, zomwe ndi kuphatikizika kwa kutentha kwa malekezero a chitoliro monga momwe tawonetsera pachithunzichi. Njirayi imapanga kulumikizana kosatha, kwachuma komanso koyenda bwino. Magulu apamwamba a matako amapangidwa ndi ogwira ntchito ophunzitsidwa bwino.
Kuphatikizika kwa matako kumagwiritsidwa ntchito pa mapaipi a PE mkati mwa kukula kwa 63 mm mpaka 1600 mm pamalumikizidwe a mapaipi, zolumikizira ndi zomaliza. Kuphatikizika kwa matako kumapereka mgwirizano wofanana ndi zinthu zomwezo monga chitoliro ndi zida zomangira, komanso kutha kukana katundu wautali.
4. Malekezero a chitoliro chotenthetsera amachotsedwa ndipo mbale yotenthetsera imachotsedwa mwamsanga (t3: palibe kukhudzana).
5. Kutentha kwa chitoliro cha PE kumasonkhanitsidwa pamodzi ndi kukakamizidwa mofanana ndi mtengo wachitsulo wowotcherera (P4 = P1) . Kuthamanga kumeneku kumasungidwa kwa nthawi kuti alole ndondomeko yowotcherera kuti ichitike, ndipo chophatikizira chosakanikirana kuti chizizizira mpaka kutentha kozungulira ndipo motero kukhala ndi mphamvu zonse za mgwirizano.

ew* ndiye kutalika kwa mkanda wowotcherera polumikizira.
Mikanda yomaliza yowotcherera iyenera kukulungidwa bwino, yopanda maenje ndi voids, kukula kwake moyenera, komanso kuti isasinthe mtundu. Akachita bwino, mphamvu yanthawi yayitali yolumikizana ndi matako iyenera kukhala 90% ya mphamvu ya chitoliro cha PE cha kholo.
Magawo a kulumikizana kwawotchi ayenera kugwirizanaku zofuna mu Chithunzi:
B=0.35∼0.45en
H=0.2∼0.25en
h=0.1∼0.2en
Zindikirani: Zotsatira za fusion ziyenera bekupewa:
Kuwotcherera mopitirira muyeso: mphete zowotcherera ndizazikulu kwambiri.
Kusagwirizana kwa matako: mapaipi awiriwa sali ogwirizana.
Dry-wotcherera: mphete zowotcherera zimakhala zopapatiza kwambiri, nthawi zambiri chifukwa cha kutentha kochepa kapena kuchepa kwa mphamvu.
Kupiringa kosakwanira: kutentha kwa kuwotcherera ndikotsika kwambiri.
Socket Fusion
Kwa mapaipi a PE ndi zomangira zomwe zimakhala ndi mainchesi ang'onoang'ono (kuchokera 20mm mpaka 63mm), kuphatikizika kwa socket ndi njira yabwino. Njira imeneyi imakhala ndi Kutentha nthawi imodzi kunja kwa chitoliro kumapeto kwa chitoliro ndi malo amkati a socket woyenerera mpaka zinthuzo zifika kumeneko anayamikira maphatikizidwe kutentha, fufuzani kusungunula chitsanzo, ikani chitoliro mapeto mu zitsulo, ndi kuligwira m'malo mpaka olowa kuzizira.
Zida zotenthetsera zimakutidwa ndi PTFE, ndipo ziyenera kukhala zaukhondo komanso zopanda kuipitsidwa nthawi zonse. Zida zotenthetsera zimayenera kukhazikitsidwa ndikuwunikidwa kuti pakhale kutentha kwapakati pa 240 Cto 260 ℃, zomwe zimatengera kukula kwa chitoliro. Kulumikizana kulikonse kuyenera kuchitidwa mobisa kuti mupewe kuipitsidwa kwa mafupa kuchokera ku fumbi, dothi, kapena chinyezi.
Ndondomeko ya socket fusion
1. Dulani mapaipi, yeretsani malo a spigot ndi nsalu yoyera komanso osayika mowa mpaka kukuya kwa soketi. Lembani kutalika kwa soketi. Yeretsani mkati mwa gawo la socket.
2.Scrape kunja kwa chitoliro spigot kuchotsa wosanjikiza kunja kwa chitoliro. Musakolole mkati mwa zitsulo.
3. Tsimikizirani kutentha kwa zinthu zotenthetsera, ndipo onetsetsani kuti malo otenthetsera ndi oyera.
4. Kankhirani zigawo za spigot ndi socket kuzinthu zotentha mpaka kutalika kwa chinkhoswe, ndikulola kutentha kwa nthawi yoyenera.
5. Kokani zigawo za spigot ndi socket kuchokera ku zinthu zotenthetsera, ndikukankhira pamodzi mofanana mpaka kutalika kwa chinkhoswe popanda kusokoneza mfundo. Gwirani mfundozo ndikugwira mpaka zitakhazikika. Mkanda wa weld flow uyenera kuwoneka mozungulira kuzungulira kozungulira kwa socket.

Chidziwitso: Kuphatikizika kwa socket sikuvomerezeka pamapaipi a SDR17 ndi pansi.
Kulumikizana kwa Makina
Monga njira zophatikizira kutentha, mitundu yambiri yamakina olumikizira makina ndi njira zilipo, monga: kulumikizana kwa flange, gawo lakusintha kwachitsulo chaPE-steel ...
Electrofusion
Pakujowina kophatikizana kwa kutentha, chida chotenthetsera chimagwiritsidwa ntchito kutenthetsa chitoliro ndi malo oyenera. The electrofusion olowa ndi usavutike mtima mkati, mwina ndi kondakitala pa mawonekedwe a olowa kapena, monga mu kamangidwe kamodzi, ndi conductive polima.Kutentha analengedwa monga magetsi ntchito pa zinthu conductive mu koyenera. Chithunzi 8.2.3.A chikuwonetsa cholumikizira cha electrofusion. Chitoliro cha PE cholumikizira mapaipi opangidwa pogwiritsa ntchito njira ya electrofusion chimafuna kugwiritsa ntchito ma electrofusion couplings. Kusiyanitsa kwakukulu pakati pa kutentha kwachizoloŵezi ndi electrofusion ndi njira yomwe kutentha kumagwiritsidwa ntchito.
Njira ya Electrofusion
1. Dulani mapaipi apakati, ndipo lembani mapaipiwo motalika mofanana ndi kuya kwa socket.
2. Pewani chigawo chodziwika cha spigot ya chitoliro kuti muchotse zigawo zonse za PE zokhala ndi okosijeni mpaka kuya pafupifupi 0.3mm. Osagwiritsa ntchito mchenga. Siyani zopangira ma electrofusion mu thumba la pulasitiki lomata mpaka likufunika kuti liphatikizidwe. Osakolopa mkati mwazoyenera, yeretsani ndi chotsukira chovomerezeka kuti muchotse fumbi, litsiro, ndi chinyezi chonse.
3. Lowetsani chitoliro mu cholumikizira mpaka zizindikiro za umboni. Onetsetsani kuti mapaipi ndi ozungulira, ndipo mukamagwiritsa ntchito mapaipi opindika a PE, zingwe zozungulira zitha kufunikira kuti muchotse ovality. Gwirani msonkhano wogwirizana.
4. Lumikizani dera lamagetsi, ndipo tsatirani malangizo a bokosi lowongolera mphamvu. Osasintha maphatikizidwe okhazikika a kukula kwake ndi mtundu wake wokwanira.
5. Siyani chophatikiziracho mu cholumikizira mpaka nthawi yozizirira yonse itatha.
Saddle Fusion
