Pakutsvaga tambo newaya dzakanakisa, kusarudza jira rakakodzera rekuvhara kwakakosha. Sheath yekunze ine mabasa akasiyana-siyana ekuona kuti tambo kana waya yacho inogara kwenguva refu, yakachengeteka uye inoshanda zvakanaka. Hazvishamisi kusarudza pakati pe polyurethane (PUR) nepolyvinyl chloride (PVC)Muchinyorwa chino, muchadzidza nezvekusiyana kwekushanda pakati pezvinhu zviviri izvi uye mashandisirwo anonyatsokodzera chinhu chimwe nechimwe.
Chimiro chesheathing uye basa rayo mutambo newaya
Chivharo (chinonziwo chivharo chekunze kana kuti chivharo) ndicho chikamu chekunze chetambo kana waya uye chinoshandiswa uchishandisa imwe yenzira dzakasiyana-siyana dzekuburitsa. Chivharo ichi chinodzivirira vabati vetambo nezvimwe zvikamu zvemuviri kubva kuzvinhu zvekunze zvakaita sekupisa, kutonhora, kunyorova kana makemikari uye makemikari. Chinogona zvakare kugadzirisa chimiro nechimiro chemubati wetambo akasungirirwa, pamwe nechikamu chekudzivirira (kana chiripo), nokudaro zvichideredza kupindirana kwemagetsi etambo (EMC). Izvi zvakakosha kuve nechokwadi chekuti simba, chiratidzo, kana data zviri mukati metambo kana waya zvinotumirwa nguva dzose. Kuvhara tambo kunoitawo basa rakakosha mukugara kwenguva refu kwetambo netambo.
Kusarudza jira rakakodzera rekuvhara ndiro kwakakosha pakusarudza tambo yakanakira kushandiswa kwega kwega. Saka, zvakakosha kuziva chinangwa chaicho chetambo kana waya uye zvinodiwa zvayo.
Chinhu chinonyanya kuzivikanwa chekuvhara
Polyurethane (PUR) nepolyvinyl chloride (PVC) ndidzo zvinhu zviviri zvinonyanya kushandiswa pakuisa tambo newaya. Pakutarisa, hapana musiyano uripo pakati pezvinhu izvi, asi zvinoratidza hunhu hwakasiyana hunoita kuti zvikodzere kushandiswa kwakasiyana. Pamusoro pezvo, zvimwe zvinhu zvakawanda zvinogona kushandiswa sezvinhu zvekuisa tambo, zvinosanganisira rabha yekutengeserana, thermoplastic elastomers (TPE), uye makemikari epurasitiki akakosha. Zvisinei, sezvo zvisinganyanyi kuwanda pane PUR nePVC, tichangoenzanisa izvi zviviri mune ramangwana.
PUR - Chinhu chinonyanya kukosha
Polyurethane (kana kuti PUR) inoreva boka remapurasitiki akagadzirwa kuma1930 ekupedzisira. Inogadzirwa nemaitiro emakemikari anonzi addition polymerization. Zvishandiso zvemafuta zvinowanzova petroleum, asi zvinhu zvezvirimwa zvakaita sembatatisi, chibage kana shuga beet zvinogona kushandiswawo mukugadzirwa kwayo. Polyurethane ithermoplastic elastomer. Izvi zvinoreva kuti dzinochinjika kana dzichipiswa, asi dzinogona kudzokera kuchimiro chadzo chepakutanga kana dzichipiswa.
Polyurethane ine hunhu hwakanaka hwemakanika. Chigadzirwa ichi chinodzivirira kupera, chinodzivisa kucheka uye chinodzivisa kubvaruka, uye chinoramba chakachinjika kunyangwe patembiricha yakaderera. Izvi zvinoita kuti PUR ive yakakodzera kushandiswa kunoda kufamba kwakasimba uye zvinodiwa zvekukotama, zvakaita sekudhonza cheni. Mukushandiswa kwemarobhoti, tambo dzine PUR sheathing dzinogona kutsungirira mamiriyoni ekukombama kana simba rakasimba rekutenderera pasina matambudziko. PUR inodzivirirawo mafuta, zvinonyungudutsa uye mwaranzi ye ultraviolet. Pamusoro pezvo, zvichienderana nekuumbwa kwechigadzirwa chacho, haina halogen uye haidzoreri moto, izvo zvakakosha kune tambo dzakanyoreswa neUL uye dzinoshandiswa muUnited States. Tambo dzePUR dzinowanzo shandiswa mukuvaka michina nefekitori, otomatiki yemaindasitiri, uye indasitiri yemotokari.
PVC - chinhu chinonyanya kukosha
Polyvinyl chloride (PVC) ipurasitiki yakashandiswa kugadzira zvigadzirwa zvakasiyana kubva kuma1920. Inobva mukugadziriswa kwegasi re vinyl chloride. Kusiyana ne elastomer PUR, PVC ipolymer ye thermoplastic. Kana chinhu chacho chikakanganisika chiri kudziyiswa, hachigone kudzoserwa pachiri chepakutanga.
Sechinhu chinofukidza jira, polyvinyl chloride inopa mikana yakasiyana-siyana nekuti inokwanisa kugadzirisa zvinodiwa zvakasiyana nekuchinja chiyero chayo. Kukwanisa kwayo kurema hakusviki paPUR, asi PVC inodhurawo zvakanyanya; Avhareji yemutengo wepolyurethane yakapetwa kana. Pamusoro pezvo, PVC haina hwema uye haipindi mvura, acid uye zvinhu zvinochenesa. Ndicho chikonzero nei ichiwanzo shandiswa muindasitiri yechikafu kana munzvimbo dzine hunyoro. Zvisinei, PVC haina halogen, ndosaka ichionekwa seisina kukodzera kushandiswa mukati. Pamusoro pezvo, haina mafuta, asi hunhu uhwu hunogona kuwanikwa nemakemikari akakosha.
Mhedziso
Zvese zviri zviviri polyurethane nepolyvinyl chloride zvine zvazvakanakira nezvazvakaipira semidziyo yekubatanidza waya netambo. Hapana mhinduro chaiyo yekuti ndeipi michina yakanakira kushandiswa kwega kwega; Zvakawanda zvinoenderana nezvinodiwa nemunhu mumwe nemumwe. Mune zvimwe zviitiko, midziyo yekubatanidza yakasiyana zvachose inogona kuva mhinduro yakanaka. Saka, tinokurudzira vashandisi kuti vatsvage mazano kubva kune nyanzvi dzinoziva hunhu hwakanaka nehusina kunaka hwezvinhu zvakasiyana uye dzinogona kuyerana.
