Ulwelwesi Tyvek: incazelo, izici kanye kwenkululeko isicelo

abakhi abangochwepheshe namuhla ujwayelene izinto kamakhi Dupont. Zenziwa e Luxembourg bayigubungele imikhakha eminingi, kufaka phakathi:

• ezolimo;
• ukwakhiwa;
• amandla;
• umkhakha ukudla;
• electronics.

Nokho, sihloko sigxile ulwelwesi gidrovetrozaschitnyh, ezihlinzekwa ukudayiswa izinhlobo eziningana.

incazelo

Ngo emakethe yasekhaya, inkampani inikeza Dupont ungangenisi amanzi izinto, okuyinto akhiqizwa ngaphansi kwegama lomkhiqizo "Tyvek". Sinenkosi ifomu imiqulu icwecwe, kanye izici lobuchwepheshe zingahlukaniswa zibe izinhlobo ezilandelayo:

• "Soft".
• "Solid".
• "Isiliva okuqinile".
• "Supro".
• "Teyp.

Ungangenisi amanzi amafilimu babe kakhulu umhwamuko permeability, umthengi ke eyaziwa njengendlela ulwelwesi okusheshayo. Lezi izindawo zikuvumela ukwenza indima gidrovetrozaschity ukwahlukanisa nezinkuni ukufulela izakhiwo. Ulwelwesi "Tyvek" Imiphumela pair of ukwahlukanisa ungqimba ngaphandle kumiswa ukufingqa phezu yendwangu. Kugcine uphefumula maqondana isembozo ukufulela ungqimba. Ngenxa yalesi sizathu, ulwelwesi isetshenzisiwe kakhudlwana futhi umhlobiso olungaphambili lwesonto.

Ulwelwesi "Tyvek" ungachazwa ukuthi kungekho umswakama ingena ngaphakathi, akusho unqobe ungqimba ifilimu: ngenkathi emoyeni ugobhozela ngenxa yayo umusi eliphezulu permeability yesendlalelo. Uchaza efanele ikakhulukazi zonke izinhlobo Dupont ungangenisi amanzi.

izakhiwo Key

Ulwelwesi "Tyvek" ngenkuthalo lisetshenziswe Hydro nokuvikelwa imimoya izakhiwo ezimele kanye nekahulumeni ngenxa yokuthi ukuthi ungqimba zokuzivikela obusebenzayo has a ukushuba ukusebenza pretty umxhwele. Lokhu ipharamitha bengase bazikhandlele 450 microns, okubonisa ukuthi ngempumelelo umsebenzi impahla ngesikhathi umjikelezo wokuphila.

Ulwelwesi olumelana emisebeni ultraviolet, ngoba ifilimu kusekelwe polyethylene. Uma inkinga nozakwabo ukuqhathanisa ulwelwesi, lona wamuva kuyoba more sensitive okushisa aphakeme. Ngokuqondene 'Tyvek "ulwelwesi, okwazi othola ukuchayeka okushisa afinyelela ku-100 ° C. Ngaphezu kwalokho, ukusetshenziswa yayo ka umthengi ungagcina i kontrobreshetke owengeziwe. Indaba ine ngezinga eliphezulu okusheshayo, ngakho-ke zingafakwa heater ngaphandle obumba igebe. Operating lolwakha eside ukwanda, kanye lokusebenza kuhle kwegezi lesi sakhiwo.

Ububanzi "Tyvek okuqinile"

Uma unquma ukuthenga ulwelwesi okusheshayo, kufanele uzijwayeze lokuqala nokusetshenziswa futhi izici eziyisisekelo. Ngokuqondene 'Tyvek Solid ", le nto kuyinto ifilimu underroof okuyinto liye landa ngamandla. It kungenziwa wabeka phezu izakhiwo ukufulela ukwahlukanisa, okuzokwenza ukwethula igebe ukupholisa.

Ulwelwesi sinamandla kakhulu, ngakho-ke ingasetshenziswa ezakhiwe futhi umoya kwesihenqo mbumbulu kanye isitini izindlu zangasese, kanye mbumbulu zezakhiwo lokhuni. Lesi sakamuva kungenzeka kunemisebenzi zamapulangwe. Ulwelwesi "Tyvek okuqinile" zingafakwa ngisho ezakhiwe uphahla abandayo kanye ophahleni nge double ukupholisa igebe. Ngesikhathi esifanayo kuyoba khona umthwalo emoyeni, kodwa ngisho yena akakwazi kulimaze ngendaba engaphansi-ukufulela.

Lokhu ulwelwesi esiwuhogelayo ingenye ezivame kakhulu zophahla ingaphandle izindlu zangasese. Isetshenziselwa eRussia engu-15 edlule. Indaba has a ungqimba yazalwa okusezingeni eliphezulu amandla polyethylene. It has a isakhiwo eliyingqayizivele futhi ihlinzeka umhwamuko ukudluliswa izinga phezu bonke ubuso. Kusukela sibonga ukwakhiwa ukuze ukuhoxiswa umswakama ngokweqile kanye purlins nemishayo yokhuni ahlale omile. Ulwelwesi "Tyvek okuqinile" ibekwe eceleni elimhlophe phansi, iphethini kufanele zibheke phezulu. Le filimu has a isisindo ongaphakeme, ngakho-ke kulula sasivumela ukuba abeke phezu kophahla.

Ukucaciswa "Tyvek okuqinile"

Lokhu kwaziswa uyakwazi ukuvikela hhayi kuphela ukumelana nomoya, kodwa imvula. It kungokwalabo isigaba flammability-T4. Flammability libhekisela isigaba B2. Amandla eqine kanye nakuyo yonke nail 90 futhi H 85, ngokulandelana. Amanzi ikholomu, okuyinto ethatha phezu okubalulekile kungenzeka ilingana ukuphakama 2.35 m.

I ukushuba we okusheshayo okulingana 0,03 neSd. Umhwamuko permeability kuyinto 683 g / m ² amahora angu-24. Ukumelana umhwamuko kuyinto 0, 1 m2 • ihora • Pa / mg. Ulwelwesi "Tyvek", izimfanelo okumele ukukusiza wenze izinqumo ezinhle, kungenziwa eziqhutshwa at okushisa ezisukela - 40 kuya + 100 ° C. Material enesisindo 82 g / m ^2, ukushuba ka 0,22 mm. Omunye roll has a isisindo 6 kg. Ubukhulu bayo m 50x1,5 (75 m ^2).

Ububanzi "Tyvek Soft"

Lokhu nokuvikela ulwelwesi esiwuhogelayo ingasetshenziswa zifudumele Uhlaka izindlu ujenga izindonga nge zamapulangwe. Sebenzisa izinto esengeziwe uphahla bamisa, ezithinta igebe ukupholisa. Ukubeka impahla kungaba kwenziwe noma yiluphi uhlangothi.

Uma umbuzo mayelana engeli, ukuthambekela kwabo kungase kube 15 ° noma ngaphezulu. Ezindaweni lapho i ukugqagqana kufanele prokleivat Indwangu itheyiphu ngesisekelo butyl zenjoloba. Ububanzi igebe ukupholisa kumele kube 50 mm. Igebe ukupholisa kontrobreshetku sekudingeka ukuba kubunjwe ukuthi uzokuvumela ukudlula mahhala umoya.

Lokukhuphula wumoya ulwelwesi "Tyvek" Kudingeka usebenzise wesitimela. Ukudla noma izipikili abakwazi ubambe izinto. Shiya ke kulesi sifundazwe, emvuleni akuvunyelwe. Uma elisophahleni akuyona ngci noma isisi abanazo izimbotshana futhi izimbobo ingavuthi ukwahlukanisa ezimanzi kungaba namerznut ice phezulu. Ulwelwesi kungenziwa kwesokunxele elangeni izinyanga 4, kepha hhayi ngaphezulu.

Ukucaciswa "Tyvek Soft"

Okungenhla ungangenisi amanzi ulwelwesi "Tyvek Soft" zingafakwa ophahleni mansard. It kungokwalabo isigaba combustibility G4, ikilasi flammability B2 kusebenza. amandla eqine we ubude kanye nobubanzi 165 kanye 140 EN.

Amanzi ikholomu wenza indaba ungaba ukuphakama 1.85 m. Ezinkulu zenza ukuthi ungangeni okusheshayo kuyinto 0, 02 neSd. Permeability amahora 24 safinyelela 744 g / m ^2. Ukumelana umhwamuko elilingana 0,09 m 2 • ihora • Pa / mg. Ukuhlolwa kwenziwa ngokuvumelana GOST 25898-83. Ukumelana Thermal ilingana umkhawulo we indaba kusuka - 40 kuya + 100 ° C. Ulwelwesi ukala 58 g / m ^2. Uhlonze lwalo kuyinto 0.18 mm. Omunye roll has a isisindo 4.5 kg. Ubukhulu bayo m 50x1,5 (75 m ^2).

Izindleko ulwelwesi

Ulwelwesi "Tyvek" nge intengo ruble 68. ngamunye imitha square, ingahlala iminyaka engu-50. Indaba akuyona anobuthi. Kuziwa eRussia evela eJalimane. By endleleni, lokhu kungani abathengi abaningi bakhetha lokhu okubalulekile wumoya, ngoba kuyahlangabezana nezindinganiso European izinga.

Ulwelwesi "Tyvek Soft" ungakwazi ukuthenga i-ruble 6200. Ukuze lokho kwaziswa ukuze umsebenzi, kubalulekile ukuqinisekisa ukufakwa efanele. Ngakho, lapho lokhuni izakhi lath iphathwa amakhemikhali, kufanele ezisele yomile amahora angu-24. Ukuze ukufakwa 'Tyvek Soft "ukusebenzisa wesitimela.

isiphetho

Umusi permeable ulwelwesi inendima enkulu ekuvikelweni izakhiwo ukuthi kungaba zokuhlala noma zezimboni.
