Munyika inogara ichishanduka yekuvaka nehuinjiniya, kutsvaga zvinhu zvakasimba uye zvakasimba kwakakosha. Pakati pezvinhu zvitsva zvakabuda mumakore achangopfuura, mapaipi ane polyurethane-lined akagamuchira tarisiro huru yekugona kwavo kuvandudza kusimba kwemapaipi echikamu chechikamu. Ichi chinyorwa chinoongorora kuti kubatanidzwa kwe polyurethane linings kunogona sei kushandura zvikamu izvi zvekugadzirisa, zvichiita kuti zvive zvakasimba uye zvinobudirira mune zvakasiyana-siyana zvekushandisa.
Hollow chikamu chemaitiro mapaipi anoshandiswa zvakanyanya mukuvaka, zvivakwa uye maindasitiri zvikamu nekuda kwechimiro chavo chetubular uye yunifomu yemadziro ukobvu. Izvo zvakagadzirirwa kugovera zvinotakura mutoro uye zvakanakira kutsigira zvimiro zvakaita semabhiriji, zvivakwa uye scaffolding. Nekudaro, rimwe rematambudziko anotarisana nemapombi aya kukonzeresa corrosion, kupfeka uye kubvongodzwa, kunyanya munzvimbo dzakaoma. Apa ndipo panopinda polyurethane linings.a
Polyurethane i polymer inoshanda zvakasiyana-siyana inozivikanwa neayo akanakisa emuchina zvivakwa, zvinosanganisira yakakwirira kusimba simba, kuchinjika, uye kuramba makemikari uye zvakatipoteredza zvinhu. Kana polyurethane ichishandiswa sechidzitiro chehollow chikamu chemaitiro mapaipi, inogadzira chipingamupinyi chinodzivirira chinowedzera kusimba kwepombi. Ichi chigadziko hachingodziviri kuparara kunokonzerwa nehunyoro uye makemikari, asiwo kunoderedza kupfeka kubva kune abrasives, kuwedzera hupenyu hwebasa repombi.
Imwe yemabhenefiti akakosha epolyurethane lined pipendiko kukwanisa kwayo kutsungirira mamiriro ezvinhu akanyanyisa. Mumaindasitiri akadai semigodhi, oiri uye gasi, uye manejimendi emvura yetsvina, mapaipi anowanzo kuratidzwa kune zvinoparadza zvinhu uye zvinokurisa. Iyo polyurethane lining inoshanda sechipingamupinyi, ichidzivirira simbi yepasi kubva pakuora uye nekuona kuti kurongeka kwepombi kunoramba kuripo. Uku kusimba kunoreva kuderera kwemitengo yekuchengetedza uye kushomeka nguva, kuita polyurethane lined pombi mhinduro inodhura kumabhizinesi.
Pamusoro pezvo, zvimiro zvisingaremi zve polyurethane zvinoita kuti gollow chikamu chechimiro pombi zvive nyore kubata uye kuisa. Zvishandiso zvechinyakare zvinogona kunge zvakakura uye zvakaoma kushanda nazvo, zvichikonzera kuwedzera kwemitengo yevashandi uye zvirongwa zvepurojekiti zvakawedzerwa. Kusiyana neizvi, pombi ine polyurethane-lined iri nyore kutakura uye kuisa, kugadzirisa maitiro ekuvaka uye kuvandudza kushanda kwepurojekiti yose.
Chimwe chinhu chikuru che polyurethane lined pombi ndeyekuita kwavo kwakasiyana-siyana. Iwo anogona kugadziridzwa kune chaiwo zvinodiwa, kusanganisira ukobvu hwakasiyana hwemachira, mamakisi akasiyana e polyurethane, uye tsika hollow chubhu saizi. Uku kuchinjika kunoita kuti vave vakakodzera kune dzakasiyana siyana dzekushandisa, kubva pakuvaka kwekugara kusvika kune makuru maindasitiri mapurojekiti.
Pamusoro pezvakanaka zvinobatsira, mapaipi ane polyurethane-lined anobatsirawo mukusimudzira kwakasimba. Nekuwedzera hupenyu hwesevhisi yemapombi ezvimiro uye kuderedza kudiwa kwekugara uchitsiviwa, zvitsva izvi zvinobatsira kuderedza marara uye kushandiswa kwezviwanikwa. Pamusoro pezvo, maitiro ekugadzira simba-anoshanda ane hukama ne polyurethanes anobatsira kuderedza kabhoni tsoka, izvo zvinoenderana nekukura kwekusimbisa kune inoenderera maitiro ekuvaka.
Muchidimbu, kubatanidzwa kwe polyurethane linings mune hollow chikamu chechimiro pombi inomiririra kufambira mberi kwakakosha muhunyanzvi hwezvinhu. Nekuwedzera kusimba uye kupa dziviriro kubva mukuora uye abrasion, polyurethane lined pombi dziri kushandura mamiriro ekuvaka nehuinjiniya. Sezvo maindasitiri ari kuenderera mberi nekutsvaga mhinduro dzinovandudza mashandiro achideredza mitengo, kutorwa kwepombi dze polyurethane lined zvinogona kukura, zvichigadzira nzira yekusimba uye inoshanda zvakanaka.
