Ndechipi chiri nani kuita
PTFE chubhu nePU chubhu zvese zvinoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana, asi nzvimbo yekushandiswa kwezviviri izvi haina kufanana. PTFE chubhu inoshandiswa munzvimbo dzekushanda dzakanyanya kunyanyisa, uye saizi yacho yakakwanawo, maindasitiri anoshanda akafara kupfuura PU chubhu. PU pombi yakakodzera kushanda pasi pekumanikidzwa nekupisa kwakajairika. Nekuti zvinhu zvayo zvakapfava uye zvinonamira, inogona kukotama painoda. Yakakodzera nzvimbo dzakamanikana kana nzvimbo dzine radius yakakura yekukotama.
Zvinotevera ndizvo zvinotsanangurwa zvakadzama nezvemhando mbiri dzemachubhu:
Chubhu yePTFE:
Pipe yePtfe ipombi yakakosha yakagadzirwa nezvinhu zvePTFE mushure mekubuda nekupwanya, kuomesa, kupisa zvakanyanya, uye kuumba. Polytetrafluoroethylene (PTFE) ine kugadzikana kwakanaka kwemakemikari, senge:
1. Haipindi kupisa kwakanyanya uye kumanikidzwa kwakanyanya. Inogona kushandiswa kwenguva yakareba pa -65℃ ~ 250℃ pasi pekumanikidzwa kwakajairika. Mushure memaawa 1000 ekurapwa kupisa kwakanyanya pa 250℃, hunhu hwayo hwemuchina hahuzoshanduki zvakanyanya.
2. Inodzivirira ngura uye inodzivirira kukwegura, inogona kutsungirira maasidhi ese akasimba, maalkali akasimba, maoksijeni akasimba, uye haizosanganisike nezvimwe zvinonyungudutsa zve organic.
3. Kudzivirira kupisa. Nekuti PTFE haina polarity, inodzivirira kupisa uye haina mvura inonyunguduka, ipurasitiki yakanaka kwazvo yemagetsi.
4. Kukwana kwekukweshana kwakaderera. PTFE ine kukwashana kwakaderera zvikuru. Chinhu chakanaka chinodzivirira kukweshana uye chinozvizora chega. Kukwana kwayo kwekukweshana kwakasimba kwakaderera pane kukwashana kwakasimba. Nokudaro, ine mabhenefiti ekudzivirira kutanga kwakaderera uye kumhanya zvakanaka kana ikashandiswa kugadzira mabheyaringi.
5. Haibati moto, haina chepfu, yakareruka, inochinjika zvakanaka uye ine zvimwe zvinhu, ine mashandisirwo akasiyana-siyana, haisi nyore kukuvadza, inoshanda kwenguva refu, hapana chikonzero chekuitsiva kakawanda ndicho chinhu chinonyanya kukosheswa.
Chinangwa chepombi yePU:
Inoshandiswa zvakanyanya mumotokari, mundege, muhydraulics, mupneumatics, munjanji, mukugadzira chikafu, mumidziyo yekufambisa mvura, mukufambisa makemikari, mukugadzira uye mukugadzira petrochemical, muchina wemagetsi unochengetedza ngura, nezvimwewo.
Hosipa yePolyurethane:
Chubhu yepolyurethane ichubhu yePU, yakakamurwa kuita chubhu yakaoma nehosipaipi, chubhu inoonekera, nezvimwewo. Chinhu chikuru ndechekuti chubhu yakapfava uye inogona kuwana radius diki yekukombama. Nekuda kwekureruka kwayo nekupfava, iri nyore uye inochinjika kushandisa. Mahosipaipi ePU anonyanya kushandiswa kumapombi emhepo, mapombi emvura nemapombi anoendesa zvinhu zvine simba rekushanda uye tembiricha. Asi kana tichienzanisa nemapombi ePTFE, mapombi ePU anowanzo kukwegura uye hydrolysis uye ane hupenyu hupfupi hwekushanda. Kugadzikana kwemakemikari kwakaderera, senge:
1. Tembiricha yekushanda iri pakati pe -20° ne +60°;
2. Kudzivirira ngura kwacho hakuna kusimba, hakugoni kutsungirira maasidhi akasimba uye alkali, uye kunosangana nyore nyore nezvigadzirwa izvi zvemakemikari.
3. Kumanikidzwa kwekushanda kuri mukati me10kg chete, izvo zvisingagone kushandiswa munzvimbo yekushanda ine kumanikidzwa kwakanyanya.
4. Inodzivirira kupfeka zvakanyanya, ine mashandisirwo akasiyana-siyana mukutakura zvinhu.
5. Nharaunda yekukombama idiki. Nekuti pombi yePU yakapfava uye ine kutwasuka kwakanaka, yakakodzera kuvaka pombi.
6. Chubhu yePU ine kujeka kwakanyanya, uye mamiriro ekuyerera kwemvura pakati nepakati anoonekwa zvakajeka.
Chinangwa chepombi yePU:
Yakakodzera maindasitiri, kurima, chikafu, mishonga, mainjiniya ehurumende, hove, kurima gungwa, kudiridza mubindu, mafuta asingakanganisi uye mamwe minda. Kana ichida kuchengetedza hupenyu hurefu hwebasa, inofanira kunge iri pasi pemutemo wekushanda uye nharaunda. Kana tembiricha ichikwira, kumanikidzwa kwekushanda kunofanira kudzikira zvinoenderana. Kana muganho ukadarika, hose inogona kuputika. Tembiricha yemvura yakanyanya kana kuti mvura ine mitengo yemakemikari inoparadza, izvo zvinogona kukonzera kuti hose iparare, tembiricha yenzvimbo yekushandira yakanyanya kana nzvimbo yekushandira ine magasi emakemikari, izvo zvinogona kukonzera kuti hose iparare, ichengetwe munzvimbo ine hunyoro kana nguva yekuchengetedza yapera. Nguva refu, ichaisa hydrolyze kana kuchembera hose, izvo zvinogona kukonzera kupwanyika.
