本发明涉及有套管件保温和设备保温的改进，用于保证管件或设备的保温稳定性、防止外界因素和外力(包括气候)的不良影响并防止材料在保温条件下的腐蚀。
背景技术
第4,838,968和4,954,202号美国专利公开了用刚性材料制造带V形槽的保温体的方法和设备。在公开的内容中，输送机将如矿棉的刚性或半刚性板材输送到各制造步骤，其中，在板材的一个表面上应用背衬材料，而在相对的表面上设置限定于板材中的一系列V形槽，这些V形槽延伸至背衬层但不损坏背衬层。该设备和方法在制造带V形槽保温体时，允许根据具体的应用对V形槽的间距进行调整和控制，从而能够将如此调整的保温板材贴合在曲面上。
希望提供一种适于粘结或粘附保护套的带V形槽保温体，并希望提供用于带V形槽保温构件上的预连接保护套(从而形成带V形槽复合结构)，从而这两个部分结合在一起能够对保护套的特性相对现有技术进行改进。另外，由于带V形槽复合结构只需要一个安装步骤，从而降低了成本并缩短了安装时间。现有的带槽保温构件中没有保护套，因而必须在现场安装护套。另外，制造带槽保温部件的现有方法无法使保温部件与保护套牢固地粘结。
通常保护套只是简单地固定或绑扎而不是粘结在工业保温体上，因为大多数工业保温体本身易碎、多灰尘、较脆和多纤维，而这种特性不允许保温体与保护套直接粘结。只有在围绕管件或设备安装保温体后才能安装保护套，从而降低了安装的速度。另外，在将保温体和保护套固定在一起后，在保温体和保护套之间还存在很小的间隙。保护套的移动会破坏气密性并有可能在保温体中吸收或凝结水或水蒸气或其它的电解液，从而导致保温层下腐蚀(CUI)。希望提供的保温体适于均匀地粘结或粘附保护套。这样会允许在工厂环境下应用保护套，从而极大地减少现场(例如通过减少使用的工具、人工和材料)的安装时间(和成本)。
本发明旨在满足现有技术领域中的以上要求和其它方面的要求。
发明内容
在本发明的一个方面中，具有多个V形槽的被涂覆的保温体包括挠性的保护套，以限定扁平的可成形的复合保温体。
在本发明的另一个方面中，保温构件包括顶面、底面和至少位于所述底面中的孔隙。粘合涂层位于所述保温构件的所述底面上，并至少部分地位于所述孔隙中。保护套材料的内表面与所述粘合涂层直接接触。多个V形槽间隔地位于所述保温构件的顶面，并穿过所述保温构件延伸至接近所述保护套的位置，所述多个V形槽中的每一个均由一对相对的面限定，这些对相对的面选择性地能形成彼此邻接的关系，从而沿所述保护套材料的外表面限定至少一个基本弯曲的部分。
在本发明的另一个方面中，上述复合保温体能够具有位于保护套和涂覆的保温板材之间的挠性背衬层。
在本发明的另一个方面中，保温构件能够包括两种不同保温材料。上述两种保温材料彼此相邻。
还是在本发明的另一个方面中，优选地在通过V形槽加工设备在保温体上加工出V形槽后，在至少一些复合保温体的V形槽的一个面上涂覆有粘合材料。当带V形槽保温体成形后，V形槽上一个面上的粘合剂能够粘附到该V形槽的相对面，以保持给定形状。在另一个方面中，除复合保温体的中间V形槽外的所有V形槽的一个面均能够涂覆有粘合剂。而复合保温体的保护套层中V形槽未涂覆的部分形成铰链。从而保温体能够以平的板材的形式从制造地运输至使用地。在使用地，能够通过将V形槽块连接在一起将保温体成形。彼此连接以围绕管材的V形槽块是两个半圆形。由于节省运输费用并且方便了管件或设备表面的应用，本发明的这个特征在经济性方面是具有优势的。
还是在本发明的另一个方面中，提供了用于安装带V形槽的复合保温体的方法，其包括：提供涂敷有粘合剂的带槽的保温板材，所述保温板材具有粘结在所述粘合剂上的保护套材料，其中，所述保护套材料的一部分延伸出所述带槽的保温板材的周边，所述保护套材料包括与所述保温构件底面不接触的至少一个完整的释放层以及位于所述保护套材料的所述一部分和所述至少一个释放层之间的压力敏感粘合剂；通过弯曲所述带槽的保温板材，将所述带槽的保温板材围绕管件预成形；去除所述至少一个释放层，以便暴露所述压力敏感粘合剂；以及将所述压力敏感粘合剂固定在所述保护套上，从而以不含蒸汽的方式围绕所述管件，从而保护工件不受结构或气候损伤。
下面结合附图对本发明的实施方式进行详细描述，从中可以清楚地了解本发明的其它优点和特征。

具体实施方式
定义
本文的“保温材料”指具有低热传导率以及在高温下不会退化和破坏的材料。
本文的“刚性”描述一种在不改变(例如力的初始作用)的情况下不会与有形表面相适配的结构。
本文的“粘合层”或“粘合涂层”指所有置于保温基层上的粘合剂。本文所述的保护套与粘合剂相关联，但与保温基层上的粘合剂分离。
本文的“多重保温体”指可组成保温构件的两种不同保温材料。
“复合保温体”指包括连接到护套上的粘性层以及可选的附加背衬构件的一个或多个保温构件。
本文的“保护套材料”、“保护套层”、“保护套”或“保护套件”指防止水从中透过的覆层材料。在连接到与保温基层相连的粘合剂上之前，保护套在其一个侧面上具有丙烯酸粘合剂，其用于将保护套固定在带V形槽的被涂敷的保温基层上。保护套粘合剂能够包括与前述“粘合层”中的粘合剂相同或不同的粘合剂。
“涂覆的保温体”指在其至少一个表面上设置有粘合涂层的保温构件，该粘合涂层至少部分地被吸入保温构件的孔隙中从而实现之间的良好粘结。涂层至少置于与复合保温的另一层连接的表面(例如接收保护套层的表面)上。
如图1所示，V形槽加工设备10由一系列工作站组成，这些工作站沿着履带传送系统设置或在该系统的上方或附近设置。第4,954,202号美国专利中的传送系统通过引用并入本文，该系统包括竖直管形架12，在该管形架12上固定有多个滚筒14或类似物以形成传送台面16。在这些滚筒14上弹性地设置有常规的环形传送带(未示出)，该传送带由电机通过导辊驱动，使得位于系统顶部的保温构件(例如一块矿棉保温体或多重保温体)沿管形架12以箭头A所示方向纵向地移动以便进行加工。传送带系统的移动速度和各种功能由微处理器15控制，该处理器还对在给定涂敷保温体部分上切割V形槽以及切断保温体的位置和频率进行管理。
更具体地，根据最终需要的保温设计，保温构件以层叠或沿纵向方向放置在传送带上。
通过在保温板材上添加保护套，增强了对气候以及物理或结构损坏的保护能力。具有预应用护套的保温材料是理想的，因为这种材料减少了保温系统的安装时间、提高了安装的方便性并减少了人工及材料成本。例如，在安装保温体后安装保护套的情况下，需要手工地用护套将保温体包裹，然后通过绑扎将护套压靠并保持在保温体上，而且安装者的熟练程度将决定该护套所提供的气候和物理保护。预应用护套的保温系统还能实现在保养维修后重复使用保温体。
通过以下方法将各层或各部分粘结在一起是理想的，即，先在保温构件上应用粘合剂，然后在保温构件上的粘合剂还具有粘性时将保温构件粘结在背面具有粘合剂的保护套上。保护套的背面具有丙烯酸粘合剂，该丙烯酸粘合剂与保温层上的粘合层粘结。在成形机13中正确成形后，保温构件在工作站17处被喷涂粘合剂，接着在工作站19处将保护套22应用在涂敷的保温构件上。如图所示，能够通过以下方式应用保护套，即，剥离保护释放层23而暴露出保护套22背面的粘合剂。喷涂在保温构件上的粘合涂层使保温构件和保护层无间隙地彼此接触，使得护套在被安装后能够保持不动。保护套能够直接应用在涂敷有粘合剂的保温构件上，或者粘附在如第5,310,594号美国专利所述类型的挠性背衬层上，该背衬层又与涂敷的保温构件接触。通常，通过利用保温构件上的粘合剂和保护套背面上的粘合剂，将保护套粘附在涂敷的保温构件上。
与第5,310,594号美国专利中的作为保温构件结构性支承的背衬层不同，本发明提供了保护套层，该保护套层的多重功能包括：防止保温体(例如管件或设备)和工作部件受到气候以及物理损伤，以及为保温构件提供结构支承。保护套层的增强功能使得复合保温体中不再需要附加的背衬层，尽管本发明的另一个方案提供了用于带V形槽复合保温体中的背衬层和保护套层。仅做支承的背衬层一般由粗玻璃纤维(glass matt fabric)形成。由于粗玻璃纤维本身是多孔的，因而不能用作保护套。
当复合保温体20通过锯切站11时，在其未涂敷表面上加工V形槽，这些V形槽进入并穿过涂敷的保温构件50的未涂敷部分，但不穿透保护套层22(或者如果设置了背衬层和保护套层的话，则不穿透背衬层)。可选地，之后将连接带24应用在复合保温体20上。
在本发明中，在工作站17处，在保温材料5的一个表面上设置粘合剂，然后该涂敷的保温体50就以这样的形式进入加工V形槽的工作站11。在工作站19处，能够在粘合层上设置保护套22，并且可选地，在类似工作站19的另一个工作站处连续地设置弹性背衬层，优选地，该另一个工作站位于加工V形槽的工作站11上游。
参考图2和2A，图1的复合保温体20显示为层叠结构40，其中相似元件以相似的数字标记。至少在保温构件46的底面45上设置粘合层44，以形成涂敷的保温体50。说明性地，展开图中的粘合层44在几何上是稳定的，但其实际上是在保温构件46上应用的解决方案。该粘合层使保温构件46与保护套42均匀地相互接触。
在置于保温构件上后，因为粘性层最小程度地被吸入保温层，因此其绝热特性不会改变。
在保温体的一种制造方法中，能够用刷子将粘性涂料应用在保温构件的外表面上，以形成涂敷的保温构件。或者，通过低压喷涂将粘合涂层应用在保温构件的外表面上(如图1所示)。
优选地，保护套42选自Venture Tape公司(Rockland，MA)提供的VENTURECLADTM 1577(五层)或1573(十三层)系列的层压式铝膜/聚酯膜。然而本发明能使用任何的保护套。VENTURECLADTM保护套包括压敏粘合层，并能在无中间层的情况下直接应用在涂敷的保温构件上。如有必要，能够使用如油漆辊的辊子将应用的护套展平。优选地，在保温构件涂敷粘合剂后且在粘合剂还具有粘性时，立刻在保护套上涂覆粘合剂。保护套还包括释放层23，在将保护套应用到涂覆的保温构件上之前，将释放层23从工作站22处去除，使得保护套的压敏粘合层暴露出来。一旦释放层被去除，保护套就适合于粘附并粘结在涂覆的保温构件上。
从需要的粘合涂层的厚度、保温体的形状以及对粘合层的非均匀性要求方面看，上述涂敷方法及其组合是优选的。例如，在向复合保温体喷涂时，其边缘可能未被涂敷，但是使用刷涂就能涂敷保温体外表面不能被喷涂的部分。应用粘合层后，(粘贴有背衬/保护套的)涂敷的保温体能够沿着设备10向锯11移动(见图1)以限定V形槽。V形槽(以用户定义的间隔)位于复合保温体的非涂敷表面上。
可选地，可通过时间受控制地在保护套层的外表面上以均匀的间隔布置多个带状件24，以使得带状件伸出复合保温体20的前边缘(leading edge)大约1.5英寸的长度。当检测到保温体的后边缘(trailingedge)后切断该带状件，使该带状件再伸出该材料大约1.5英寸的长度。同时，在该带状件上应用胶带28，以使带状件牢固地粘贴在复合保温体上。
在其它实施方式中，没有在背衬层或者保护套的外表面上应用带状件。在这些实施方式中，如前述第60/887,892号美国临时申请所述，利用具有释放层的粘合悬垂物将保护套安装在保温体上，该粘合悬垂物在安装保护套前保持不动。由释放层保护的保护套能够密封保护套的相邻部件之间或层叠层之间的所有暴露边缘或接缝。
在图2和2A中所示出的本发明的一个实施方式中，复合保温体40包括具有顶部43和底部41表面的保护套层42、粘合层44以及具有顶部47和底部45表面的保护套层42。能够在保护套层42和粘合层44之间设置可选的附加背衬层(例如未示出的粗玻璃纤维背衬层)。至少在保温构件46的底部45上设置粘合层44。还能设置一个或多个附加保温构件46’，其被叠放在第一保温构件46的顶层47上，或者与保温构件46并排放置。在并排放置的布局中，至少在两个保温构件的底面上涂敷粘合涂层。
在复合保温体40上加工V形槽后，根据每个待包裹的特殊形状中V形槽的间距和频度，实现对各种不同形状物体的包裹。能在复合保温体40上加工V形槽以便围绕圆形或椭圆形结构闭合。如果如图2B所示在保温体上均匀地加工V形槽，那么能将该复合保温体如图4所示地用于包裹圆形管件81。
在图2C示出的实施方式中，复合保温体上加工有非均匀的V形槽。该保温体包括具有紧密排列的V形槽51的第一长度，接着是不具有V形槽的一段长度53，然后是具有紧密排列的V形槽51的部分，最后是一段不具有V形槽的长度53。当包裹或闭合带V形槽的部分时，该绝缘材料会具有如图3所示的椭圆形状，从而可以覆盖椭圆形物体，比如多个电缆或电缆桥架、工字钢或类似物。
在某些实施方式中，复合保温体中的保温构件由矿棉或玻璃丝纤维构成。在另一些实施方式中，复合保温体能够包括具有相似或不相似特性的相邻保温材料，由这些保温材料组成保温构件(即多重保温体)。相邻的保温材料能够是均匀的，或者是随宽度变化的。另外，保温材料能够具有相似或不同的机械和保温特性。包括两个或更多相邻保温材料的复合保温体能够具有水平或垂直方向上的V形槽。
在图5和5A所示的一个实施方式中，涂敷的保温材料粘贴在挠性背衬构件60上，而该挠性背衬构件60又粘贴在保护套上。在该实施方式中，通过如第5,310,594号美国专利所述的粘贴在外层背面的线束，或者如第60/887,892号美国临时申请所述的(在应用前由释放层保护的)压力敏感粘合层，能够使复合保温体围绕如管件的结构保持不动。在其它实施方式中，可通过线束或压力敏感粘合层的组合使复合保温体围绕如管件的结构保持不动。
根据本发明，在大多数多重的保温体中没有必要将各种保温体粘结在一起。由于V形槽和保护套的定位，通常不利用粘合剂而将保温体保持在一起。当然，如果需要，在不同保温体间使用粘合剂是可能的，并且，如果期望的话，是在所有材料位于传送带上时使用粘合剂。能够使用与在工作站17处使用的相同粘合剂将各种保温体粘结在一起。
图6示出了本发明的一个实施方式，其中，在保温体上加工V形槽后，将如压力敏感粘合剂(与图1所示在工作站17应用的粘合剂类似或不同)的粘合剂S应用在V形槽的一个面上。如果将粘合剂应用在所有V形槽的一个面上，那么当安装过程中闭合保温体时，V形槽会在闭合的构造中自动地粘结在一起，从而简化了保温体应用和使用。但是，如图7所示，如果位于保温体中间的一个V形槽C上没有粘合剂，那么在该V形槽位置上的保护套将提供铰链H。这样，如图7所示，当保温体形成闭合构造时，其中间部分形成了两个半部之间的铰链，从而如图8所示，允许简化的在管件81或类似物上的安装。在第5,310,594号美国专利中也描述了利用在带V形槽材料上选择性地使用粘合剂而形成铰链及其优点，该专利的内容通过引用并入本文。第3,084,403号美国专利描述了与通常为刚性的带槽材料一起利用铰链结构。
明显地，通过使用具有各种特性的保温材料可对本发明的多重或单一保温体进行定制，从而使复合或单一保温体具有从大约四英尺至小到几英寸的宽度。在其它实施方式中，保温体包括层叠保温材料，其中“层叠”是指一种材料叠放另一种材料顶部上的不同材料的堆叠，这种层叠材料由以下刚性材料成对构成：矿棉和泡沫玻璃；矿棉和聚亚胺酯泡沫；矿棉和陶瓷纤维；或者由如下的刚性材料和挠性材料成对构成：矿棉和陶瓷纤维板；矿棉和挠性聚亚胺酯泡沫。使用三种或更多种保温体也是可能的。在这些实施方式中，矿棉成分的厚度能在大约0.5英寸到大约4英寸之间变化，而另一种成分的厚度在大约0.5英寸到大约4英寸之间，这样保温体的总厚度就会在大约1英寸到5英寸之间。材料组合使得多重保温体具有一种材料的优点，如良好的绝热值，同时使这种材料的缺点最小化，如因其脆性及对不同形状的非适应性而难以和如泡沫玻璃的材料相适配。
另外，如果在需要时使用成本较高的如陶瓷纤维的材料，并在不需要使用陶瓷纤维时使用较为经济的如矿棉的材料，那么使用两种或更多种的保温体就具有经济性。例如，最靠近被保温管件的保温材料受热最多，而离管件越远，材料受热则越少，这样就可以在离管件较远处使用热值较低的材料，比如矿棉。
还是在其它的实施方式中，诸如矿棉、硅酸钙、珍珠岩或玻璃纤维的保温材料由如珍珠岩的不同材料带在纵向或机器方向分隔。这种复合结构具有矿棉的例如成本较低的优点(但矿棉的结构强度低)，同时具有珍珠岩或硅酸钙的高结构强度。这种增强的结构使保温体具有抗高负荷(包括管件重量)的能力，和/或尤其使该结构在不同的位置被踩踏。
明显地，除在选择位置具有高密度材料带外，保温体还能包括一半的一种刚性材料以及一半的另一种刚性材料。或者，能够使用例如矿棉一种保温体用于进行涂敷以及接下来的V形槽加工。
当将保温体层可放置在管件上并使一种例如珍珠岩的材料置于顶部，这样就能使整个结构被踩踏而不损坏保温体。本领域内的技术人员会理解，可通过对材料进行各种改变来利用成本和特性不同的各种材料。
另外，在加工V形槽时可以不一定要使用多重保温体，也能对例如单一的保温材料加工V形槽。在优选的实施方式中，该保温材料包括矿棉。通过正确选择材料使得绝缘材料应用于对以下对象的覆盖：管件、商用润滑油路、商用和工业用电缆桥架、如工字钢等的结构钢架、大型化学料罐以及基本上任何需要结构完整性的结构。
根据本发明的保温构件可包括矿棉。该保温构件可包括两种或更多层叠的不同保温材料，例如可包括三种不同的保温材料。如果将不同的材料用于保温构件，这些材料则可为层叠的，并且其中一种、两种或全部的材料可为刚性的。当保温材料包括至少一种刚性材料的情况下，该材料可为矿棉。当具有第二刚性材料时，其可为例如泡沫玻璃、聚亚胺酯泡沫或刚性陶瓷纤维层。当第二材料为挠性材料时，其可为聚亚胺酯泡沫或挠性陶瓷纤维板。
对于本领域技术人员而言，能够对本发明做出在本发明描述的范围内的各种改变。在本领域技术人员能力范围内所做出的这些改变形成本发明的一部分，并包括在本发明权利要求及其等效内容的范围内。
