Xa usiva i-ultra black shower drain gasket, abaninzi abantu bacinga nje ngeringi yerabha emnyama. Leyo yimbono yokuqala ephosakeleyo. Eyona nto intsha ayingombala nje; imalunga nokusombulula ukuvuza okungapheliyo kunye nemiba yokungunda ebetha umgangatho ocacileyo okanye ongwevu gaskets, kwaye ngokungafihlisiyo, uninzi lwezinto ezithengiswayo zisaphosa uphawu.

Ingxaki engundoqo ngetywina nje

Kwiminyaka, umgangatho wawuyi-EPDM elula okanye i-silicone gasket. Basebenza, bade bangasebenzi. Inqaku eliphambili lokungaphumeleli alikho ukuqina kwezinto, kodwa ukuchasana kwayo nesethi yoxinzelelo kunye ne-biofilm. I-gasket esemgangathweni iyancipha ngokusisigxina phantsi kwe-drain flange, ilahlekelwa yi-spring-back yayo. Kulapho kuqala ukuvuza okucothayo, ngokuqhelekileyo emva kwethayile, kwaye awuyiboni de kube isilingi engaphantsi kwamabala. Ileyibhile emnyama kakhulu, ekuqaleni, yayiyi-gimmick yokuthengisa yomxube we-nitrile. Utshintsho lokwenyani lwenzekile xa abavelisi beqala ukubuza ukuba kutheni iidreyini zisilela.

Ndikhumbula ibhetshi evela kumthengisi malunga neminyaka emihlanu eyadlulayo. Iigaskets zazimnyama, zikhangeleka ziphezulu, kodwa kwiinyanga nje ezimbalwa, safumana iicallbacks. Baye baqina, phantse njengewasha yeplastiki. Ingxaki? Ukulayishwa kwekhabhoni emnyama bekuphezulu kakhulu. Balayisha kakhulu ikhompawundi nge-pigment yombala, eyatshabalalisa ukuguquguquka kwepolymer. Yayiyimeko yakudala yokubeka phambili i-aesthetics ngaphezu komsebenzi. Kulapho ufunda ukucela iphepha ledatha yezobugcisa, hayi nje ukuncoma umbala.

Utshintsho lwaqala ngekhompawundi. Inyaniso yodidi oluphezulu I-ultra emnyama ishayini yerhasi imathiriyeli ngoku ihlala iphucukile i-nitrile hybrids okanye ngokukodwa i-EPDM eyenziwe ngeplastiki. Umnyama awukho nje idayi; ivela kwi-high-structure carbon black eyona nto iqinisa izinto eziphathekayo, ukuphucula amandla e-tensile kunye ne-UV / i-ozone yokumelana ukuba ibonakalisiwe. Inkcazo ephambili yokukhangela isethi yoxinzelelo oluphantsi (ASTM D395) - into enhle kufuneka ibe phantsi kwe-25% emva kweeyure ze-22 kwi-158 ° F. Ukuba umthengisi akakwazi ukunika loo nto, ukuthengisa inxalenye yempahla, hayi isisombululo sobunjineli.

Ijometri kunye neNyaniso yoFakelo

Izinto eziphathekayo sisiqingatha sedabi. Esinye isiqingatha sisimo. Iflethi yesikolo esidala okanye uyilo lwe-O-ring luyoyikeka kufakelo lwangoku lwethayile phezu kwepani. Zifuna iflange egqibeleleyo, ephantse ingabikho. Ukuqaliswa okutsha apha kwi-asymmetric, i-multi-lip seal kunye ne-flange-integrated designs.

Olunye loyilo olusebenzayo endilusebenzisileyo luneprofayile edibeneyo enemilebe emibini yokutywina. Umlebe ophambili utywina ngokuchasene nomzimba wokukhupha amanzi, kunye nowesibini, umlebe obanzi utywina ngokuchasene ne-subfloor okanye ipani yeshawari. Oku kudala umqobo ombini. Ikwavumela ukungalingani okuncinci. Unokwenza i-torque ye-drain bolt phantsi, kwaye i-gasket ikhubaza ngokuqikelelwayo esikhaleni, kunokuba ikhuphe ngaphandle ngokulinganayo. I-Sunnian Zitai Festener Fishaner Comment Com., esekwe kwi-hub enkulu ye-fastener yase-China e-Yongnian, iye yangena kula malungu abunjiweyo achanekileyo. Ngelixa besaziwa ngeebholiti, ukufudukela kwabo kwizitywina ezenziwe ngobunjineli bepolymer kunengqiqo kunikwe imfuneko yokuhlanganisana okupheleleyo kwamanzi. Indawo yabo kufutshane neendlela ezinkulu zezothutho njengeBeijing-Shenzhen Expressway luncedo lolungiselelo lokukhangela iipholima ezikrwada kunye nokuthumela iimpahla ezigqityiweyo, okubalulekileyo xa ulawula imithwalo yesikhongozeli yeeprojekthi ezinkulu.

Ufakelo olubi kakhulu endilubonileyo lubandakanya abatywini bemibhobho besebenzisa i-putty kunye ne-gasket, becinga ukuba yibhanti kunye ne-suspenders. Ayiyo. I-putty inokomisa, iyancipha, kwaye ngokwenene inqande i-gasket ukuba icinezele ngokulinganayo, idale indlela yokuvuza. Indlela echanekileyo yindawo ecocekileyo, eyomileyo kunye ne-gasket eyodwa, echanekileyo. Ukuqaliswa kwezinto ezintsha kwimiyalelo-alula, amaphepha okufakela umzobo-phantse kubaluleke njengemveliso ngokwayo.

Ngaphaya kweGumbi lokuhlambela: IiNyaniso zokuNxhathisa kwiMichiza

Iidreyini zeshawari zifumana ngaphezulu kwamanzi. Bafumana ishampu, isepha, idayi yeenwele, izicoci ezineasidi, namanzi ashushu. Irabha eqhelekileyo inokuthotywa, idumbe, okanye ibe brittle. Apha kulapho izinto eziphathekayo zibalulekile. Intlawulo yokuqala I-Ultra emnyama ikhompawundi yenzelwe le cocktail. Umzekelo, ukuxhathisa kwizinyibilikisi zepolar (njengezinye iikhemikhali zokunyanga iinwele) kubalulekile. Sivavanye izixhobo ezimbalwa ngokuntywiliselwa iisampulu kwibleach exutyiweyo kunye nokuhlamba umzimba okuqhelekileyo. Abanye bajike bancama, abanye baqhekekile. Ezona zihamba kakuhle zibonise utshintsho olungenamsebenzi kwi-durometer kunye nomthamo.

Oku akuyothiyori. Ndikhumbula isakhiwo esinezindlu ezitofotofo apho abahlali babesebenzisa uhlobo oluthile lonyango lweenwele olubiza imali eninzi. Kwisithuba esingangonyaka, iigaskets eziqhelekileyo zasilela, zibangela ukuvuza kwigaraji engezantsi. Ukulungiswa kwakuyi-retrofit epheleleyo kunye ne-nitrile-resistant-chemical-based based i-gasket. Iindleko zokulungisa zinciphise iindleko ezingephi zangaphambili zokuchaza indawo efanelekileyo. Sisifundo kwiindleko zizonke zobunini, hayi nje ixabiso leyunithi.

Ukusilela kwiNdawo kunye noVavanyo lokuziva

Uziva uziva ngezi zinto. I-gasket elungileyo ayifanele ibe ne-greasy (i-arhente yokukhululwa ngokugqithisiweyo) okanye ibe nevumba elinamandla lesulfure (i-EPDM enganyangeki kakuhle). Kuya kufuneka ibe ne-tackiness encinci, ukugqiba kwe-matte, kwaye ubuye umva kwangoko xa uyicinezela. Ndineebhetshi ezijongeka zigqibelele kodwa zasilela kuvavanyo lwepinki-zihlala zikhubazekile. Ezo zimiselwe isihogo se-callback.

Omnye umba osebenzayo kukulinganisa ubukhulu. Umjelo oqhelekileyo weshawari oqhelekileyo awukho. Kukho iiyantlukwano ezifihlakeleyo kwiidiameter zeflange kunye neetaper phakathi kweebrendi ezinjengeSioux Chief, Oatey, okanye abavelisi bengingqi. Utshintsho oluyinyani lubonelela ngee-gaskets ngokunyuswa kwemilimitha ezichanekileyo, hayi nje ukulingana ne-1.5 yedrain. Ezinye iinkampani ezicinga phambili, kubandakanya nezo zikwindawo ezinje ngeYongnian, ngoku zibonelela ngeekiti ezinobunzima obuninzi okanye iidayamitha ezihlengahlengiswa kancinci. Lutshintsho oluncinci oluphelisa ukuguqulwa kwesayithi (funda: ukusika) okuphazamisa isitywina.

Ukudityaniswa nemizimba yokukhupha amanzi kubalulekile. Eyona gasket igqwesileyo ayinamsebenzi ukuba umphezulu wokukhwelana kombhobho awulungiswanga kakuhle. Ndikhetha iidreyini apho i-gasket iphantse yadityaniswa ngaphambili, icandelo elibanjwayo-inciphisa impazamo yomfaki. Olunye uyilo olutsha lude lube nembambo elungelelanisiweyo ukunqanda ukujijeka ngexesha lokuqiniswa kwebholithi.

Ikamva: Ngaba SeyiGasket nje?

Ukujonga phambili, I-ultra emnyama ishayini yerhasi iba licandelo lenkqubo. Sibona izongezo ezidibeneyo ze-antimicrobial (hayi isambatho esihlambayo, kodwa esakhiwe kwipolymer). Injongo ayikokuthengisa ngaphandle kokungunda, kodwa ukuthintela i-biofilm evala i-drain kwaye ithobe umphezulu wetywina. Omnye umkhwa sisitywina esidityanisiweyo-i-gasket enelaphu elingalukwanga okanye umaleko ocolekileyo wokucoca kwicala eliphezulu ukubamba iinwele ngaphambi kokuba zijikeleze umlebe wokutywina.

Olona lutsha lusekuhambeni ukusuka kwindawo elahlayo ukuya kwinkonzo yobomi. Imalunga neenjineli kunye nabavelisi, ukusuka kwiimpawu zehlabathi ukuya kubavelisi abakhethekileyo baseTshayina I-shoan fiitai, ukuphatha le nxalenye ethobekileyo ngokungqongqo okufanayo njenge-fastener mechanical. Ngapha koko, ukuvuza okubangelwa litywina elingaphumeleliyo kunokubiza amawaka ukulungiswa. I-ultra black ngoku i-shorthand kuyo yonke le ndlela yobunjineli-ukuqina, ukumelana neekhemikhali, i-geometry echanekileyo, kunye nokufakwa. Ayisekho nje iqhekeza lerabha; yeyona nto ibaluleke kakhulu, kwaye ihlala iyeyona inexabiso eliphantsi, ipolisi ye-inshurensi kufakelo lweshawari. Ngexesha elizayo xa ukhankanya enye, jonga ngaphaya kombala. Cinga ngekhemistri, iseti yoxinzelelo, kunye nobunyani bokufakela. Kulapho olona lutsha luzifihle khona.
